Chadwick B05 Lecture Theatre

I’m pleased to announce the launch of our new UCLQ Visitor Seminar Series with our first guest speaker, Joaquin Fernandez Rossier (http://inl.int/members/31).

Joaquin will be giving his seminar on Monday, 17 November 2014, from 1-2pm in the Chadwick B05 Lecture Theatre.  Please see below for further details, including the title and abstract for his talk.

Short Bio: Joaquin Fernandez-Rossier is a researcher at the International Iberian Nanotechnology Laboratory (INL) and an associate professor at the University of Alicante.  He works on the broad field of condensed matter physics with emphasis on nanoelectronics and nanospintronics on a variety of materials including graphene and other layered two dimensional materials, magnetic semiconductors and topological insulators. He is the coordinator of the Marie Curie ITN project on Spintronics in Graphene (www.spinograph.org). He has published more than 80 indexed research papers, including 1 Nature, 2 Nature Materials, 16 PRL, 38 PRB, cited more than 2100 times (h=26, Research ID C-3910-2009). He has graduated 4 PhD students.

Title: Magnetic Graphene

Abstract: Spontaneous magnetic order is expected to occur in graphene in two different situations:  at the zigzag edges at zero applied field and in the Quantum Hall regime, at half filling.   In this talk I will discuss our recent [1,2] and not so recent [3-5] theoretical understanding of magnetic order in graphene in these two situations, the experimental state of the art, and the experiments that would conclusively confirm, or else, recent claims [6] about room temperature edge ferromagnetism in graphene.[1]  J. L.
