Crystalline electric field (CEF) analysis of the magnetization data of Dy0.73Tb0.27Co2 in the temperature range 20-200 K is reported. The components of the g-tensor are calculated from the wavefunction for the CEF ground doublet. The contributions to the quadrupole interaction at the Dy nucleus are evaluated and hence the total hyperfine energy levels of the 161Dy nucleus are calculated from the fit results to the magnetization data. © 1997 Elsevier Science Ltd.

Magnetization studies and crystalline electric field effects in Dy0.73Tb0.27Co2

Solid State Communications

X-ray-diffraction studies carried out on Tb0.27Dy 0.73Fe2-xCox (x=0,0.5,1.2,2.0) revealed that all compositions investigated retained the C-15 cubic Laves phase structure. Magnetization and electrical resistivity measurements were carried out in the temperature range 77-800 K. Anomalies observed in the resistivity measurements have been identified corresponding to spin reorientation transitions occurring in this system. Some of these transitions have also been observed in the magnetization data. Magnetostriction and magnetomechanical coupling coefficient were measured on samples of x=0, 0.5, and 1.2 prepared by arc melting as well as arc melting followed by zoning using an induction furnace. Magnetostriction and coupling coefficient were found to decrease with increase in cobalt concentration. Magnetostriction data on zoned samples revealed a change in the easy direction of magnetization from [111] to [100] in the case of x=0.5.
