An easy axis distribution and a crystal texture in a warm extruded anisotropic Mn-AI-C magnet were determined by X-ray diffraction analyses. Resulting values in (001) pole density are treated by introducing a normalization condition in order to determine the quantitative values. The distribution is expressed only as a function of tilt angle 4>. and is found to consist of the following Gaussian distribution term and constant. P(4)) = 3.42 exp [-4>2/(2X30.8 2 ) 1 + 0.11. Magnetically measured Mr/Ms = 0.88 is significantly higher than 0.74, the value calculated from this total distribution when assuming that the magnetization in every grain points in the direction of each easy axis. The crystal texture is approximated by [OOIJ single fiber texture. The inverse pole figure indicates that among twelve {Illl <112) twin systems, four twin systems which preserve CuAu I type superstructure are responsible for the formation of this texture. PACS numbers: 75.50. -y, 81.40.Ef J.

Abstract. Permalloy epitaxial films of (111), (100), and (110) orientations and a polycrystalline thin film are prepared. Sinusoidal waveforms of magnetostriction are observed when the polycrystalline and the (111)-oriented epitaxial films are measured under rotating magnetic fields ranging from 10 to 1000 Oe. On the contrary, the (100)-and the (110)-oriented films, respectively, show a triangle waveform and a waveform consisting of a mixture of triangular and sinusoidal shapes under low magnetic fields. The waveform variation is interpreted by considering the magnetization structure of magnetically unsaturated film with an in-plane magnetic symmetry related with the crystallographic orientation. The waveforms deformed from sinusoidal shape vary to sinusoidal with increasing the magnetic field. Magnetically saturated (100)-and (110) , and 6 " 10 -6 for the (111), the (100), the (110) epitaxial and the polycrystalline films, respectively.
