The time evolution of the first order magnetic phase transition in Dy-4 percent Y alloy
Abstract
The first order magnetic transition of spiral to ferromagnetic structure of Dy-4 percent Y alloy has been investigated by means of synchrotron x-ray diffraction. The development of the ferromagnetic phase could be studied by x-ray diffraction measurement for the observation of the hexagonal to orthorhombic crystal distortion accompanying the first order magnetic transition. Below (Tc), the ferromagnetic and spiral phases coexist and the development of the ferromagnetic phase exhibits a time dependent behavior and is proportional to log(t) except in the early stage of the phase transition.
