Title

Probing g-factor anisotropy in CeB6 by neutron scattering

Abstract

CeB6 is a heavy-fermion metal with a simple cubic crystal structure, characterized by the rich magnetic-field-temperature phase diagram. An external magnetic field B enhances TQ and rapidly suppresses TN. The AFQ state in CeB6 has been extensively studied as it represents an example of a magnetically hidden order, associated with the ordering of magnetic quadrupolar moments. Very recently, ESR measurements revealed a significant anisotropy of the g-factor as a function of the applied field direction. Our neutron results show significant difference of the resonance energy upon change of the field direction. Qualitatively similar behavior can be reproduced using the theory, and corresponding calculations were done by A. Akbari. Branches have a very clear anisotropy with respect to the field direction. We already managed to observe the onset of the second branch for fields parallel to [110] above ~12T. In accordance with the calculations, we expect to find a similar second branch with a magnetic field applied along [111], but at lower field values, therefore we will be able to follow its field dependence and to check how good is consistency with theory.
