Dynamical ground state in the XY pyrochlore Yb2GaSbO7

ORAL

Abstract

The magnetic ground state of the pyrochlore Yb2GaSbO7 has remained an enigma for a long time. Here I will discuss the synthesis and characterisation of Yb2GaSbO7 that enabled us to revisit the nature of the magnetic ground state. Through DC and AC magnetic susceptibility, heat capacity, and neutron scattering experiments, we observe evidence for a dynamical ground state that makes Yb2GaSbO7 a promising quantum spin liquid candidate. This state is quite fragile, being tuned to a splayed ferromagnet in a modest magnetic field H = 1.5 T.
