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