Nahuel Statuto

My name is Nahuel Statuto and I have a Degree in Mathematics and Master in Theorical Physics from Universitat de Barcelona. Now, I performing a PhD under the supervision of Dr. Ferran Macià, in the group of Multifunctional Oxides and Complex Structures (2016 – 2019)

A new memory

In a radio interview (Pa Ciència la Nostra – Radio Sants) Ignasi Fina talks about the realisation of a memory device able to be connected to any PC via standard USB connection based on an antiferromagnetic material.  The realisation of this proof of concept device might be an important step on for antiferromagnetic spintronics.

Giant Optical Polarization Rotation Induced by Spin-Orbit Coupling in Polarons

In this work, published in Physical Review Letters, we demonstrate that the polarization of light is changed dramatically when its energy resonates with the polaron-hopping energy of self-trapped electrons.  In the presence of spin-orbit coupling, the self-trapped hopping electron may reverse its spin producing a large gyrotropic effect, which is observed close to room temperature. The effect is observed in La23Ca13MnO3 thin films and, plausibly, should be present in other manganites.

Since straining this kind of materials can change the polaron concentration, our finding suggests a route to mechanical or electro-mechanical control of the magneto-optical effect, paving  the way to unconventional magnetoelectric effects.

This work has been highlighted with a Synopsis on the Physics website:

 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.

Mathieu Mirjolet

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!

Ferran Macià

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.
