NMR Investigation of the Breathing Kagome Lattice in Li<sub>2</sub>In<sub>1-x</sub>Sc<sub>x</sub>Mo<sub>3</sub>O<sub>8</sub>

ORAL

Abstract

We report 7Li NMR measurements on Li2In1-xScxMo3O8 at concentrations x=0, 0.6 and 1. The results are compared with those of other groups on the end members of the series [1] and with previous work using muon spin rotation (µSR) [2]. The sample dependence and the effects of pressure on the NMR spectra and on the temperature dependence of the spin-lattice relaxation will be discussed, as well as their implications for possible spinon excitations in the spin liquid regime at intermediate Sc concentration.
