Fingerprint of phase transition across the magnetic compensation temperature in Pr_1-xGd_xAl₂ alloys

Abstract

The magnetization compensation phenomenon is observed for Sm1-xNdxScGe at x=0.09 at a temperature ∼90 K in a small applied magnetic field, which establishes the ‘spin surplus’ status of magnetic moment of Sm in the host matrix. We also noted that the sample profiles in QD SQUID magnetometer become asymmetric in some situations indicating significant contributions from multiple moments higher than the dipole moment. We have successfully accounted for them using a fitting procedure the higher order magnetic moments
