Magnetocaloric effect in CeCo4B compound

Large magnetic entropy change above 300 K in (La0.56Ce0.14)Sr0.3MnO3 perovskite

“…2, we plot the H/M vs. M 2 curves to clarify the order nature of the phase transition. The plots of H/M vs. M 2 show a positive slope in the complete M 2 range, which confirms that our doped sample exhibits a second-order FM to PM phase transition [12,13].…”

Magnetocaloric effect in terbium diboride

“…According to the Banerjee criterion [15,16], a magnetic transition is expected to be of the first order when the slope of H/M versus M 2 plot is negative (i.e. B < 0), whereas it will be of the second order when the slope is positive (i.e.…”
