TL;DR: In this paper, the temperature dependences of the magnetocrystalline anisotropy constant K 1 and the magnetostriction constants? 100 and? 111 were measured for Fe-Si-Al alloy single crystals.
Abstract: The temperature dependences of the magnetocrystalline anisotropy constant K 1 and the magnetostriction constants ? 100 and ? 111 were measured for Fe-Si-Al alloy single crystals in the composition range 4 to 6 wt% Si, 2 to 5 wt% Al, balance Fe, after being slowly cooled from 1200°C or quenching from 1200°C. The crystal structure of these single crystal samples was determined by electron diffraction. The large difference in the magnitudes of K 1 =9.1×103 erg/cm3 for 4.8 wt% Si, 5.0 wt% Al, bal. Fe alloy, and K 1 =9.1×105 erg/cm3 for 4.7 wt% Si, 3.8 wt% Al, bal. Fe alloy was found to be connected with the difference in their crystal structures. The ? 100 =0 and ? 111 =0 equal-value line were identified on a composition diagram. The concentration of the alloy at which the second peak in ?m occurs is located along the ? 100 = 0 line Moreover, this second peak alloy may have the Do 3 structure.
