CSU Master's student investigated magnetic and electronic properties of new Geisler alloys

Obambi Miche Antipas, a master's student at the Department of Radiophysics and Electronics, Faculty of Physics, CSU, has studied previously unexplored Geisler alloys. The results were reflected in his master's thesis ‘Magnetic and electronic properties of Geisler alloys Mn2YSn (Y=Sc, Cr, Mn): an ab initio study’.

Using a computational software package, the young scientist modelled the equilibrium states of Mn2YSn compounds (Y=Sc, Cr, Mn) using the given lattice parameters and obtained a set of characteristics of these states, including the density of electronic states, magnetic exchange interaction parameters and others.

‘The results obtained can be applied in the field of electronics, spintronics, for data storage devices,’ said the master's student. - There are no special difficulties in the research, because I have a wonderful supervisor Mikhail Zagrebin, who guides, prompts, and I find a solution’.

The topic of the paper contains the concept of ab initio, which means calculating the properties of materials by relying on density functional theory. According to Mishe, he uses this method because of the rather high reliability of the results.

‘Studying the properties of Geisler alloys is an interesting and popular topic, but we don't have such a field in Congo, so I decided to be the first person in my country to discover new knowledge in this field.’ said Mishe.

Now Mishe is enrolling in a postgraduate programme to continue his studies and research. The young man has a large number of publications and a grant project is planned.
