Hall Effect in Manganese Antimonide

Abstract

The temperature dependence of normal and extraordinary Hall coefficients, and of specific resistivity in MnSb is measured by the application of alternative current and d.c. magnetic fleld. Contrary to ferromagnetic metals the observed materials have the large normal Hall coefficient above magnetic saturation, the values of which is positive and the order of 10 -9 m 3 /C., and the observed ones decrease with decreasing temperature. The rations R 0 /ρ are almost constant at various temperatures below the Curie point and in the different samples. ( R s /ρ) versus ρ curve seems to be linear. It may be thought to confirm the reliability of theory.
