摘要：
The Fermi surface of the pnictinide compound SmSb2 has been studied by means of the Shubnikov-de Haas and de Haas-van Alphen quantum oscillatory effects in pulsed magnetic fields to 60 T. Spectral analysis of the magnetoresistance and magnetization shows several closed-pocket regions of the Fermi surface. Closed pockets of 65, 190, 700, and 760 T are determined to account for the Fermi surface. The respective effective masses were found to be of the order of the free electron mass.
