Abstract:
Measurements made on the EPR spectrum of a pair of interacting nearest neighbor neodymium ions in lanthanum ethyl sulphate show that the interaction is predominantly dipolar but that there is also a non-dipolar interaction. A semiquantitative discussion is given of the possible origins of this non-dipolar contribution including superexchange, electric quadrupole-quadrupole, and virtual phonon exchange interactions.
