Resumo
The first experimental investigation of the magnetic and magnetistriction properties of the alfa-manganese monosulphide (α-MnS) with the cubic (NaCl-type) structure and antiferromagnetic transition at T=150 K are presented in the temperature range of 4.2–300 K at applied magnetic field up to 90 kOe. It is found, that the field dependences of the magnetization and longitudinal magnitostriction of the α-MnS single crystal have an anomalies, which are correlated with the anomalies of its dielectric permittivity. The spin-flop (SF) transition with Hsf ~ 50–70 kOe governed by the magnetic easy-plane anisotropy was observed in the temperature range below 130 K. Isotermal investigations show that the longitudinal magnetostriction and dielectric permittivity in external magnetic fields reveal its value change of 10-3 at Hsf.
