ESR on Sm3 ions in mixed-valence compound

Abstract

In ESR study on Sm3+ ion in the intermediate-valence single crystals SmB6 spectra are first found static Jahn-Teller effect on the rare earth ion. The energy of Jahn-Teller splitting is estimated.

ON THE CHEMICAL STABILITY OF THE STRUCTURE AND PHYSICAL CHARACTERISTICS OF THE HIGH-TEMPERATURE SPINTRONIC COMPOSITE EuO:Fe UNDER NORMAL CONDITIONS

“…The fraction of ferromagnetic clusters in it is much smaller, which agrees with the impossibility of formation of solid substitution solutions of Eu on Fe at the EuO lattice. The display of the ionic state of iron in the composite should be considered as impurity centers forming Eu-Fe-O clusters as a result of a possible chemical interaction of them with an europium cations at accordance by the mechanism of indirect d-fexchange [7].…”
