Abstract

In this study, the magnetic and magnetocaloric effects of Ni0.95Zn0.05Cr2O4 have been investigated systematically. The distinct magnetic phases in different temperature zones were identified using a combined analysis of Arrott plots and virgin magnetization curves. The magnetocaloric phenomenon is sensitive to the spin correlation of the nickel and chromium magnetic sublattices within each distinct temperature zone, as is reflected by the modulation of the magnetocaloric sign. This unique oscillatory like magnetocaloric effect within the multiferroic phase may indicate the possibility of a multicaloric effect in Ni0.95Zn0.05Cr2O4.
