摘要：

The effect of hydrostatic pressure on magnetic entropy change in a magnetic field, Delta Sm, in Fe7Se8 single crystals is determined. The application of hydrostatic pressure shifts the spin-reorientation transition temperature, TSRT, to lower temperatures, similar to the action of a magnetic field applied perpendicularly to the c-axis. The magnetization of Fe7Se8 in a field parallel to the c-axis monotonically decreases under increasing pressure. Delta Sm and the refrigeration capacity of investigated crystals strongly depend on TSRT and thus on hydrostatic pressure. Experimental results are described in the frame of a one-ion model of magnetic anisotropy.
