Structural and magnetic properties of pseudoternary Nd2(Fe1−xCux)14B compounds

Abstract
Magnetic and crystallographic measurements have been made on new pseudoternary compounds Nd2(Fe1−xCux)14B in order to study the systematic variation of magnetic properties with Cu substitution. X‐ray powder diffraction data indicate that the tetragonal Nd2Fe14B‐type phase exists only for x≤0.05. Partial replacement of Fe by nonmagnetic Cu significantly decreases the saturation magnetization value with little change in ferromagnetic Curie temperature TC. Low‐temperature spin orientation temperature (Tsr) decreases from 135 K for x=0.00 to 130 K for x=0.03, and 122 K for x=0.05, and the tilt angle of the easy magnetization direction from the tetragonal c axis decreases accordingly.
