Structural and magnetic properties of Pr0.3Tb0.7Fe1.9-xMnx Ribbons

Abstract

The structural and magnetic properties of Pr0.3Tb0.7Fe1.9-xMnx ribbons have been investigated using X-ray diffraction, vibrating sample magnetometry and the standard strain gauge technique. According to the XRD spectra, all ribbons of Pr0.3Tb0.7Fe19-xMnx demonstratea pure Laves phase, which benefits from the melt-spun technology. The Curie temperature of the Pr0.3Tb0.7Fe1.9-xMnx alloys decreases gradually from 366°C for x=0.1 to 328°C for x=0.3. Meanwhile, magnetostriction at room temperature demonstrates a maximum at x=0.1.
