Mixing effects of light and heavy rare earths in the Laves phase compounds Nd1−xTbxCo2
TLDR
In this article, the lattice constant and magnetic properties of compounds Nd1-xTbxCo2 were investigated by x-ray power diffraction and magnetic measurements, and it was shown that these compounds exhibit a field-induced metamagnetic transition from a weak ferrimagnetism to a strong ferrimagnetic transition in the vicinity of x(c).Abstract:
The lattice constant and magnetic properties of compounds Nd1-xTbxCo2 were investigated by x-ray power diffraction and magnetic measurements. The lattice constant and Curie temperature show linear variations with the Tb concentration, while the saturation moment exhibits an anomaly at a critical concentration x(c)approximate to0.33. The compounds exhibit a field-induced metamagnetic transition from a weak ferrimagnetism to a strong ferrimagnetism in the vicinity of x(c). (C) 2002 American Institute of Physics.read more
