Dielectric and Magnetic Anomalies in alpha-MnS Single Crystals at Applied Magnetic Fields

https://doi.org/10.1007/s10948-021-06045-z

Temperature and magnetic field dependences of the magnetic susceptibility and dielectric permittivity of the α-MnS single crystal with NaCl structure are first investigated at around Neel temperature and at 4.2 K and H up to 70 kOe. A relation between the investigated properties was established. The founded phenomena can be due to the magnetostriction or magnetoelastic mechanism and the spin-dependent dipole moment.
