Description

The structure and magnetic properties of Gd3(Fe1-xCox)28Nb compounds, with x ranging from 0 to 0.4, have been investigated by means of x-ray diffraction and magnetic measurement. All compounds investigated crystallize in the Nd3(Fe, Ti)29-type structure. The lattice parameters and the unit-cell volume decrease with increasing Co content x. It is found that substitution of Co for Fe leads to a significant increase in the Curie temperature from 503 K for x = 0 to 920 K for x = 0.4. Saturation magnetization gradually increases with increasing Co. All compounds show easy plane-type anisotropy. The anisotropy field Ba at 5 K obviously decreases with increasing Co content
