Abstract

From the EPR spectra of pairs of

{Ce}^{3 +}

and

{Nd}^{3 +}

ions in La

{Cl}_{3}

and La

{Br}_{3}

it is possible to isolate contributions to the interaction tensors from high-degree anisotropic superexchange interaction of the form

J_{+}^{5} (1) J_{-}^{5} (2)

and

J_{z}^{l} (1) J_{\pm}^{5} (2)

.
