Pressure effect on magnetic susceptibility of SmS in semiconducting phase: experimental study

Magnetic susceptibility $χ$ of the polycrystalline sample of samarium monosulfide was measured as a function of the hydrostatic pressure $P$ up to 2 kbar at liquid nitrogen and room temperatures using a pendulum-type magnetometer. A pronounced magnitude of the pressure effect is found to be positive in sign and strongly temperature dependent: the pressure derivatives of $χ$, d\,ln$χ$/d$P$, are $6.3\pm0.5$ and $14.2\pm1$ Mbar$^{-1}$ at 300 and 78 K, respectively. The obtained experimental results are discussed within phenomenological approaches.
