Magnetic Properties of Dilute Alloys of Scandium

Abstract

Previous experiments have shown that small quantities of cerium will induce a spin‐compensated state in the d¹ elements yttrium and lanthanum. The magnetic susceptibility of scandium alloys with 0.02–2‐at.% cerium has been measured over the temperature range of 4°–300°K. No evidence for a spin‐compensated state is found. Addition of gadolinium has been shown to polarize the scandium matrix. To study the influence of a heavy rare earth with nonzero orbital angular momentum on the polarization of the scandium matrix a series of dilute dysprosium alloys have been studied. The effect of dysprosium is found to be similar to that of gadolinium. Also the influence of the nonmagnetic alloying elements titanium and thorium on scandium has been investigated in order to separate the various factors affecting the magnetic properties of dilute scandium alloys.
