The first-order magnetic transition of spiral to ferromagnetic structure of Dy-4%Y alloy has been investigated by means of Synchroton 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 behaviour and is proportional to log t except in the early stage of the phase transition.
