The effect of hydrogen on the magnetostriction of rare-earth compounds TbxDy₁₋xFe₂

The effect of hydrogen on the magnetostriction of rare-earth compounds TbxDy₁₋xFe₂

The crystal structure and the magnetic and magnetoelastic properties of TbxDy₁₋xFe₂Hy (x = 0.27; 0.41; y ≤ 3) are investigated. The hydrides are obtained by the interaction of TbxDy₁₋xFe₂ samples with hydrogen gas at room temperature. It is established that the hydrides have the same cubic type of s...
