Magnetization and g Factor Measurements of Nickel-Palladium Alloys

Abstract

Saturation magnetization measurements of Ni-Pd alloys show for a Pd concentration range c, 0–50 at. %, a linear decrease of the mean atomic moment according to M = MNi−0.11c, with MNi = 0.616 μB. The extrapolated moment for Pd is 0.51 μB. Ferromagnetic resonance measurements at 35 GHz show a hyperbolic increase of the g factor with Pd addition. The calculated spin moments vary linearly as Msp = 0.56−0.17c, indicating 0.39 hole in the 4d band of Pd. The g factor of Pd would be 2.58, indicating a non-negligible orbital contribution.
