INMA Impulso: Mikhail Otrokov
INMA Impulse Seminar: ‘Combining magnetism and topology: From magnetic doping to novel interfaces and intrinsic magnetic topological insulators’
On Wednesday 25 September at 12.00 pm will be a new session of the INMA-Impulse conference series, a series of conferences that seeks to bring the most cutting-edge research to society.
During the next session we will have the presentation of Mikhail Otrokov, from the Aragon Nanoscience and Materials Institute (INMA), a joint institute of the CSIC and the University of Zaragoza, which will offer the seminar entitled: ‘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.
The session will take place on Wednesday 25 September at 12.00 noon in the Sala de Grados of the Science Faculty of the University of Zaragoza.
