Low temperature magneto-transport and magnetic properties of MnSb${}_2$Te${}_4$ single crystals

The results of a comprehensive study of MnSb${}_2$Te${}_4$ single crystals are presented. The structure, Raman spectra, low-temperature transport, Hall effect, magnetization, and magnetic susceptibility are studied. It was established that the crystals are ferromagnetic, with a Curie temperature ranging from 22 to 45,K for different samples. Hall and magnetization measurements demonstrated that the system is a soft ferromagnet, which is of interest for practical applications.
