Abstract
A change of the c-lattice parameter of Dy which is induced by magnetic fiel d along the easy direction of magnetization has been studied by X-ray diffr action in the temperature range of the helix phase. A discontinuous change of the c lattice parameter accompanying to the helix to fan or ferromagneti c transition has been observed below 170 K, but it becomes continuous chang e above 170 K to T-N. The lattice modulation with the same wave number as t he magnetic modulation has been observed at the distorted helix phase, whic h can be explained in terms of magnetoelastic effect.
