Seminario INMA – Impulso: Combining magnetism and topology: from magnetic doping to novel interfaces and intrinsic magnetic topological insulators

El miércoles 25 de septiembre a las 12.00 horas tendrá lugar una nueva sesión del ciclo de conferencias INMA-Impulso, un ciclo de conferencias que trata de acercar la investigación más puntera a la sociedad.

Durante la próxima sesión contaremos con la presentación de Mikhail Otrokov del Instituto de Nanociencia y Materiales de Aragón, INMA, instituto mixto del CSIC y la Universidad de Zaragoza, que ofrecerá el seminario titulado: Combining magnetism and topology: from magnetic doping to novel interfaces and intrinsic magnetic topological insulators

Abstract:

In this talk, I will overview the developments in the field of magnetic topological insulators (MTIs) that led to the discovery of the intrinsic MTIs of the MnBi2Te4 family that attracts a great deal of attention nowadays. First, to describe the context in which materials such as MnBi2Te4 appeared in the research arena, I will discuss the magnetic doping and magnetic proximity effect approaches of introducing magnetism into a TI. Then, the two types of novel interfaces involving MnBi2Te(Se)4 compounds will be discussed, as they are expected to show certain advantages over the latter two approaches. Next, the discovery of intrinsic MTIs of the MnBi2Te(Se)4 family will be overviewed. Finally, concerning current challenges of this field, we will consider in detail the issue of the Dirac point gap in the MnBi2Te4 topological surface state that has caused a lot of controversy recently.

La sesión tendrá lugar el miércoles 25 de septiembre a las 12.00 horas en la Sala de Grados de la Facultad de Ciencias de la Universidad de Zaragoza.
