Spin reorientation phenomena in Dy1-xYxFe11Ti alloys
Spin reorientation phenomena in the Dy1-xYxFe11Ti(x = 0, 0.2, 0.4, 0.6, 0.8 and 1) compounds have been studied by ac susceptibility and magnetization measurements on bulk and magnetically aligned powder samples. The observed concentration dependence of the spin reorientation temperatures and the temperature dependence of the cone structure of this series of compounds have been analyzed on the basis of the crystal field model. A set of crystal field parameters is proposed. © 1993.
