Main directions of studies

Investigations of the de Haas - van Alphen effect in various intermetallic compounds at  normal conditions and  hydrostatic pressure.

Main principal results, recently obtained:

Detection and investigation of the de Haas - van Alphen effect in intermetallic transition metal compounds МеВ₂, and in magnetically ordered rare-earth compounds RB₁₂ и RGa₃, the later ones are also studied under pressure up to 6000 atm.
 

Experimental equipment 

Low frequency differential magnetometer that operates at temperatures 0,5 – 4,2 К, in fields  up to 9 T. .
