Abstract

In order to characterize thermal excitations in a frustrated spin liquid, we have examined the magnetothermodynamics of a model geometrically frustrated magnet. Our data demonstrate a crossover in the nature of the spin excitations between the spin-liquid phase and the high-temperature paramagnetic state. The temperature dependence of both the specific heat and magnetization in the spin-liquid phase can be fit within a simple model which assumes that the spin excitations have a gapped quadratic dispersion relation.
