| Summary: | The first order magnetic transition of spiral to ferromagnetic structure of Dy-4%Y alloy, which is induced by both temperature and magnetic field, has been investigated by means of X-ray diffraction and magnetization measurement. The development of the ferromagnetic phase could be studied by X-ray diffraction measurement for the observation of the hexagonal to orthorohmbic crystal distortion accompanying the first order magnetic transition. Below Tc, the ferromagnetic and spiral phases coexist down to 10 K and the latter was found to be in a meta-stable state. The development of the ferromagnetic phase induced by both temperature and magnetic field exhibits a time dependent behavior and is proportional to log t. The results are discussed with the one dimensional kink model assuming the "spin slip" in the spiral phase. |
