PARAMAGNETIC RESONANCE IN RARE EARTH METALS,
Abstract
The difference between the g values of paramagnetic metals and those of free ions has been attributed to an interaction between the paramagnetic ions and the conduction electrons. G shifts have been observed in gadolinium metal and several of its alloys; namely gadolinium with yttrium, gadolinium with palladium, and gadolinium with lutetium. The g shift is generally found to be negative though it may be positive for the dilute alloys with yttrium. There would appear to be some small concentration dependence of the g value and this, togeather with the positive or negative behaviour of the g shift, is examined with respect to the Yosida and Kondo models. In this way the behaviour of the g shift can be more readily understood. In order to interpret the resonance measurements, preliminary measurements of susceptibility and magnetization were made. In Addition it was necessary to measure lattice parameters since phase diagrams for some of the alloy systems are not abailable. (Author)
