Structural and Magnetic Properties of (Nd_1‐xHo_x) ₃Fe_27.31Ti_1.69 Compounds.

Abstract

1.69 Compounds. -All title compounds with x ≤ 0.6 crystallize in the Nd 3 (Fe,Ti) 29 -type structure. Substitution of Ho for Nd leads to a contraction of the unit cell volume. Magnetic measurements indicate that the Curie temperature of the title compounds is almost independent of the Ho content, whereas the saturation moments decrease monotonically with increasing x. For all compounds investigated a spin reorientation from easy plane to easy cone occurs when the temperature decreases from room temperature to 5 K. A tentative spin phase diagram is given. -(WANG*, W. Q.; WANG, J. L.; YAN, Y.; DU, X. B.; WANG, X. F.; JIN, H. M.; J.
