Magnetocaloric effect of Er5Si4 under hydrostatic pressure

Original language description

The magnetocaloric effect (MCE) of the compound Er5Si4 has been investigated as a function of the applied magnetic field (up to 50 kOe) and the hydrostatic pressure (from ambient pressure up to 9 kbar). At constant magnetic field change, increasing the pressure up to 1.4 kbar induces a global rise of the magnetic entropy change |?Smag|, with the peak at TC 30 K growing from 14.9 to 20.1 J/kg K. Between 1.4 and 9 kbar, the size and shape of the |?Smag| VS T curve remain nearly constant but the peak movesto higher temperatures and stabilizes above 3.5 kbar at T 36 K. The increase in the magnetic entropy change occurs because of a modification of the magnetic coupling derived from the differences in the interlayer bonding in the M and O(I) states.
