Abstract
The magnetocaloric properties of the polycrystalline TmZn sample, obtained in a 2–15.4 K range temperature, under 0.1
T
magnetic field and various hydrostatic pressures, have been theoretically investigated and compared with experimental results. It has been found that the behavior indicating the first-order metamagnetic transition of TmZn has been progressively eliminated with raising the hydrostatic pressure. Moreover, the Curie temperature increases gradually with the increase of the hydrostatic pressure. The agreement between simulation and experimental results confirms that the phenomenological model can investigate thermo-metamagnetic properties in TmZn system.
