Hien, T.D. http://tainguyenso.vnu.edu.vn/jspui/handle/123456789/7027 2011-05-07T04:46:51Z 1982-01-01T00:00:00Z Title: Magnetic properties of TbxY1-xCu2 compounds at low temperatures Authors: Luong, N.H.; Duc, N.H.; Hien, T.D. Abstract: Magnetisation and susceptibility measurements are reported for the pseudobinary intermetallic compounds TbxY1-xCu2 (x = 0.1, 0.3, 0.5, 0.7, 0.9 and 1). Metamagnetic behaviour was observed at low temperatures in this system, except for Tb0.1Y0.9Cu2. The critical magnetic field and the N??el temperature smoothly decrease with increasing Y content. The temperature dependence of the magnetisation of TbCu2 was studied. The interaction parameters between Tb3+ ions were determined for the compounds investigated. ?? 1982. 1982-01-01T00:00:00Z Magnetic properties of RCu2 (R = Dy, Ho, Er) and DyxY1-xCu2 compounds Hien, T.D.

Apart from the antiferromagneticparamagnetic transitions additional transitions have been observed for HoCu2 and ErCu2 below their N??el temperatures. For the DyxY1-xCu2 compounds the dependence of the N??el temperature on the Y content has been determined. The results are discussed in the RKKY model. ?? 1983. 1983-01-01T00:00:00Z
