Investigating the Quantum vs Classical Nature of the Spin Liquid State in Yb(Mg,Zn)GaO4

ORAL

Abstract

Recently the rare earth RMM’O4 systems (where R = rare earth, M and M’ = transition or main group) have been suggested as strong spin-orbit coupled quantum spin liquid candidates. In this talk we present our recent field-dependent diffuse neutron scattering, torque magnetometry, and magneto-transport results performed on Yb(Mg,Zn)GaO4 single crystal samples. Further, we discuss the role of disorder and thermal fluctuations in explaining the observed spin liquid phenomena.
