CEF groundstate of the frustrated quantum magnets SrRE$_2$O$_4$ (RE= Dy, Ho)

ORAL

Abstract

We have measured the crystalline electric field (CEF) niveaus of the magnetic ions in the frustrated quantum magnets SrRE$_2$O$_4$ with RE = Dy and Ho by inelastic neutron scattering. SrRE$_2$O$_4$ crystallizes in a $pnam$ structure, which as four in-equivalent rare earth sites, leading to a large degree of geometrical frustration. Fitting a CEF level scheme to the experimental data has allowed us to determine the CEF ground state of this system.
