- Abstract
- We have studied the crystalline electric field (CEF) effect of the Ho1-xDyxNi2B2C system using the anisotropy and the temperature dependence of magnetic susceptibilities with magnetic field H perpendicular or parallel to c-axis, and estimated the magnetic exchange interaction constant J(ex)(perpendicular to) of rare-earth ions perpendicular to the c-axis. The crystalline electric field parameter B-2(0) the first Steven parameter and the most dominant term in this system, are determined from the J(ex)(perpendicular to) and anisotropic Weiss temperatures and then show a broad minimum around x approximate to 0.3, where superconducting transition temperature, T-C, and Neel temperature, T-N, are similar.
