摘要:
Nd2Ni2Sn crystallizes as Ce2Ni2Sn in the orthorhombic structure related to the W2CoB2-type. Its unit cell parameters are, respectively, a = 436.0(1)pm; b = 569.5(2)pm and c = 849.8(2)pm. Nd2Ni2Sn orders antiferromagnetically at T-N1 = 21.0(2)K and exhibits two other transitions at T-2 = 17.7(2)K and around 14-15K. These ordering temperatures are higher than that determined for the first time on NdNiSn (T-N = 3.0(2)K). The investigations of Nd2Ni2Sn by electrical resistivity, AC and DC magnetization and Sn-119 Mossbauer spectroscopy allow to propose a tentative field-temperature magnetic phase diagram exhibiting four different phases.
