MgV_{2}O_{4} is a spinel based on magnetic V^{3+} ions, which host both spin (S=1) and orbital (l_{eff}=1) moments. Owing to the underlying pyrochlore coordination of the magnetic sites, the spins in MgV_{2}O_{4} only antiferromagnetically order once

The magnetic ground state of the pyrochlore Yb2GaSbO7 has not been established. The persistent spin fluctuations observed by muon spin-relaxation measurements at low temperatures have not been adequately explained for this material using existing the

Publikováno v: Physical Review B. 102

A framework is presented for modeling and understanding magnetic excitations in localized, intermediate coupling magnets where the interplay between spin-orbit coupling, magnetic exchange, and crystal-field effects are known to create a complex lands

Here we present a neutron scattering-based study of magnetic excitations and magnetic order in NaYbO$_2$ under the application of an external magnetic field. The crystal electric field-split $J = 7/2$ multiplet structure is determined, revealing a mi
