Magnetic resonance as an orbital state probe

Abstract

Magnetic resonance in ordered state is shown to be the direct method for distinguishing the orbital ground state. The example of perovskite titanates, particularly, LaTiO3 and YTiO3, is considered. External magnetic field resonance spectra of these crystals reveal glaring qualitative dependence on assumed orbital state of the compounds: orbital liquid or static orbital structure. Theoretical basis for using the method as an orbital state probe is grounded.
