Room temperature magnetocaloric effect of the Cox(MnSb)1-x compounds

  The room-temperature magnetocaloric effect (MCE) of Cox(MnSb)1-x (x=0.07,0.15,0.24)alloys has been investigated.It is revealed that the Curie temperature Tc and the magnetic entropy change ΔSM are sensitive to the Co content x.When x=0.15,the MCE of Co0.15(MnSb)0.85 alloy is optimal with ΔSM=1.8 J/kg.K at 324 K under an applied magnetic field of 3 T.A second-order phase transformation occurs around Tc,and the magnetic hysteresis loss thermal lag is negligible.These features demonstrate that Co0.15(MnSb)0.85 alloy is a promising room-temperature magnetocaloric materials.
