摘要: The magnetic properties and magnetocaloric effect in R2PdSi3 (R = Dy, Dy and Er) compounds have been investigated. All these compounds possess an antiferromagnetic (AFM)-paramagnetic (PM) transition around their respective Néel temperatures. And, it is found that the Dy2PdSi3 and Er2PdSi3 compounds undergo a spin-glass behavior below Néel temperature. Under the magnetic field change of 5 T, the values of ?DS max M reach 11.8 J/kg K for Gd2PdSi3, 16.6 J/kg K for Dy2 PdSi3 and 22 J/kg K for Er2PdSi3, respectively. Especially, the values of ?DSmaxM in the Er2PdSi3
