 I’m joining MULFOX (as a RyC scientist) to work within the multifunctional oxides group. My work experience and interests are magnetism and spintronics in mesoscopic systems. Currently, I seek new types of information processing inspired on how the brain works; I consider that exploiting complexity of magnetic and electric signals at the nanoscale is an alternative approach to device miniaturization. I believe there is life outside the lab and we, scientists, must connect our work with society.

Hello there! My name is Mathieu Mirjolet. After finishing my master’s degree in Physics at the Université de Lorraine in France, I decided to join the Multifunctional Oxides and Complex Structures group of ICMAB in order to carry out my PhD.

In everyday life I enjoy travelling, reading, listening to some classical music, or just setting the world to rights with my friends and a fine whisky. Hope to see you around!

I am a research scientist with a background in mathematics and telecommunication engineering. My work experience and interests are magnetism and spin-dependence electron transport (spintronics) in mesoscopic systems, magnetic quantum tunneling and coherence in low dimensional magnetism. I am also interested in dynamical systems especially those involving magnetism. I follow an interdisciplinary research approach-contributing mostly with experimental work but also with theoretical and computational studies.

Fontcuberta

I’m mostly interested on functional oxides. These strongly correlated electronic systems display fascinating
ferroic (i.e. magnetic, ferroelectric), electric and optical properties, that have motivated my research and that
of the group I’ve led. I’m a material’s scientist and I have devoted much effort to the preparation and growth
of epitaxies of complex oxides and to the study of the relationship between their structure, microstructure and
functional properties. Nowadays, my research activity is focused on exploiting oxide thin films for efficient
data storage using magnetic and ferroelectric materials, and their potential use in photovoltaics for energy
harvesting and as transparent metallic electrodes.
I’m persuaded that oxides can play a very important role in advanced high-tech devices and I’m pushing for the
development of either new applications or new-concept devices.

Pt/BaTiO3/La0.7Sr0.3MnO3 tunnel junctions.

It is demonstrated that reversing the polarization direction of a ferroelectric barrier in a tunnel junction leads to a change of junction conductance and capacitance, with concomitant variations on the barrier height and effective thickness, both contributing to produce larger electroresistance

Lourdes Fàbrega

Cryogenic radiation detectors, working at temperatures well below 1K, are considered the next generation of instrumentation for a wide variety of applications. Among them, superconducting Transition Edge Sensors (TESs) are nowadays at the frontline. TESs are ultrasensitive microcalorimeters or bolometers useful for a very wide radiation range, from gamma-rays to microwaves and particles. Although initially developed mainly for astronomic instruments, either on ground or in space, their performances, the maturity achieved and the progress on cryogenics have open many other niches for them, in applications such as industry, materials science and quantum information. In particular, TESs have already been installed in electron microscopes and in several synchrotron lines.

My research focuses in the development (design, fabrication and characterization) of X-ray detectors based on Mo/Au-based TES, for Space and other applications, such as dark matter search or materials science. I’m also interested in the physics of these devices: indeed, in spite of the extraordinary development of TES and their achieved performances, there is still room for them to further approach the theoretically predicted limits. Specific work to this end involves understanding the nature of the superconducting transition, and electrothermal modeling to determine and reduce the so-called unexplained noise.

Electrons moving in 2D: symmetry matters

The development of today’s electronics is reaching fundamental limits and novel concepts and materials are researched to achieve ever faster and more efficient electronic devices. In this regard, oxides are well positioned, as they display a fascinating complexity of electronic phases –not present in conventional semiconductors–that may open new pathways.

The interface between LaAlO3 and SrTiO3 is the oxide quantum well (QW) par excellence, where superconductivity and magnetism emerge. In LaAlO3/SrTiO3 QWs electrons move in two dimensions forming a two-dimensional electron gas (2DEG, Box a). However, not all the electrons reside in the same QW subband (Box b) and, indeed, they behave differently depending on which orbital are they occupying. We demonstrate that the symmetry of the conduction band inside the QWs can be selected, so that the properties of electrons vary largely. In particular, we show that in the superconductive state Cooper pairs do not bind in the same way either when we change the number of electrons in the 2DEG by electric fields (Box a) or when the direction of confinement is changed (Box b). We also show that choosing the confinement plane allows manipulating the spin-dependent transport in these QWs.

Our work opens a groundbreaking route to manipulate selectively electrons in two dimensions. See more @ G. Herranz at al., Engineering two-dimensional superconductivity and Rashba spin–orbit coupling in LaAlO3/SrTiO3 quantum wells by selective orbital occupancy, Nature Communications 2014, doi:10.1038/ncomms7028.

We show that very diluted dispersions of ferromagnetic metal nanoparticles in diamagnetic hosts show a large, linear response under an applied magnetic field, which is of interest for emerging applications in sensing, integrated optical communications, and magneto-optical current transformers and transducers.  We present also a theory that describes accurately these results and that can be further extended to describe the optical properties of e.g., metal inclusions in polymers or glasses.

Quantum wells at the LaAlO3/SrTiO3 interface with tunable electron states

Quantum wells with d-electrons at the LaAlO3(LAO)/SrTiO3(STO) interface exhibit physical properties, such as superconductivity or magnetism, unseen in conventional semiconductors (Si, Ge, GaAs, …). We have demonstrated that the symmetry of the conduction band inside the QWs can be selected at whish. This opens up novel perspectives to manipulate the electronic properties of QWs at the LAO/STO interface.
