EXCHANGE POLARIZATION AND THE MAGNETIC INTERACTIONS OF RARE EARTH IONS

Abstract

Results are reported of a study of the contribution of spin or exchange polarization to the magnetic interaction of a rare earth ion with its neighbors and with its own conduction electrons. The rare earth ions carry a paired electron spin density which is negative in their outer reaches and these ions may even appear to their neighbors as having negative spins (i.e. antiparallel to the 4f spin direction). Some experimental results are discussed on this basis.
