Copper centers in KTaO3:Cu single crystals were studied by Electron Paramagnetic Resonance. We evidenced two types of single Cu2+ centers and one exchange-coupled Cu2+-Cu2+ pair centre. The spectra of pair centers show tetragonal symmetry and the exchange interaction in the pairs is ferromagnetic (S=1)

Abstract

Copper centers in KTaO3:Cu single crystals were studied by Electron Paramagnetic Resonance. We evidenced two types of single Cu2+ centers and one exchange-coupled Cu2+-Cu2+ pair centre. The spectra of pair centers show tetragonal symmetry and the exchange interaction in the pairs is ferromagnetic (S=1)

Applied Physics/Condensed Matter/Materials Science encompasses the resources of three related disciplines: Applied Physics, Condensed Matter Physics, and Materials Science. The applied physics resources are concerned with the applications of topics in condensed matter as well as optics, vacuum science, lasers, electronics, cryogenics, magnets and magnetism, acoustical physics and mechanics. The condensed matter physics resources are concerned with the study of the structure and the thermal, mechanical, electrical, magnetic and optical properties of condensed matter. They include superconductivity, surfaces, interfaces, thin films, dielectrics, ferroelectrics and semiconductors. The materials science resources are concerned with the physics and chemistry of materials and include ceramics, composites, alloys, metals and metallurgy, nanotechnology, nuclear materials, adhesion and adhesives. Resources dealing with polymeric materials are listed in the Organic Chemistry/Polymer Science category.
