Electrical and Magnetic Properties of SmSb Single Crystals at Low Temperatures

On SmSb single crystals synthesized from elements, the electrical resistance R and magnetization M were measured as functions of temperature magnetic field. A large magnetoresistance is observed over entire range 2-300 K, increasing significantly with decreasing temperature. The dependence exhibits a singularity at transition to antiferromagnetic state T N =2.3 K. At temperatures below 8 de Haas--van Alphen oscillations are in M(H) dependences, frequencies which do not change upon through . Linear extrapolation Landau indices on reciprocal field 1/B zero gives value T=2 K =0.75, indicates presence Berry phase nontrivial band topology compound. Keywords: samarium monoantimonide, magnetization, magnetoresistance, transition, Haas-van oscillations, phase.
