Study of magnetocaloric effect in half-metallic ferromagnet Co3Sn2S2

We have investigated the magnetocaloric effect of a shandite-type half-metal ferromagnet Co3Sn2S2. The magnetic entropy change -ΔSM(T,H) can be well scaled by the scaling relations, indicating that the magnetic ordering transition is of second order. The obtained exponents from the fits of field dep...

Zusammenfassung:	We have investigated the magnetocaloric effect of a shandite-type half-metal ferromagnet Co3Sn2S2. The magnetic entropy change -ΔSM(T,H) can be well scaled by the scaling relations, indicating that the magnetic ordering transition is of second order. The obtained exponents from the fits of field dependence of ΔSMmax,δTFWHM and RCP are consistent with critical behavior analysis.
