Abstract
In this work, we have investigated the effect of the substitution of Gd for Pr on the crystal structure and magnetic properties of the Pr 1-xGdxCo4B compounds for 0≤×≤1 using X-ray powder diffraction, magnetic measurements, and differential scanning calorimetry (DSC). These compounds have hexagonal CeCo4B-type structure with the space group P6/mmm. The substitution of Gd for Pr leads to a decrease of the unit-cell parameters a and the unit-cell volume V, while the unit-cell parameter c increases slightly. Magnetic measurements indicate that all samples are ordered magnetically below room temperature. The Curie temperatures determined by DSC technique increase as Pr is substituted by Gd. The saturation magnetization at 5 K decreases upon Gd substitution up to x = 0.6, and then increases again. Crown Copyright © 2008 Published by Elsevier B.V. All rights reserved.
