摘要

The crystal structure, magnetic phase transition and magnetocaloric effect in R₅CoSb₂ (R = Pr, Nd, Gd–Er) alloys are investigated. All alloys are crystallized in the Yb₅Sb₃-type orthorhombic structure. R₅CoSb₂ (R = Pr, Nd, Gd–Er) alloys undergo ferromagnetic (FM)-paramagnetic (PM) transition under 1 T. The magnetic phase transition of the R₅CoSb₂ (Gd–Er) alloys is of second-order nature, whereas the first-order phase transition takes place in the R₅CoSb₂ (R = Pr and Nd) alloys at a low temperature. For Δμ₀H of 0–5 T, the values of the maximum of entropy change (the relative cooling power) are 6.4 J/kgK (97.8 J/kg), 2.2 J/kgK (108.7 J/kg), 7.5 J/kgK (592.5 J/kg), 5.2 J/kgK (400.4 J/kg), 6.2 J/kgK (413.5 J/kg), 9.0 J/kgK (423.0 J/kg) and 10.4 J/kgK (299.5 J/kg) in R₅CoSb₂ (R = Pr, Nd, Gd–Er) alloys near the phase transition temperature.
