Low energy magnetic excitations in superconducting YbSnPd2
Abstract
The Heusler compound YbSnPd2 exhibits singular thermodynamic and transport properties, with coexistence of superconductivity and antiferromagnetism at low temperature (T<220 mK). The field and temperature dependencies of the low energy magnetic fluctuations have been studied by inelastic neutron scattering, for temperatures down to 60 mK and magnetic fields up to 2.5 T. We report the observation of a novel excitation characteristic of a magnetic-fluid in addition to the anticipated Zeeman doublet of a Γ7 crystalline electric field ground state.
