Spin-cluster excitations in the rare-earth kagome system Nd3Ga5SiO14
Abstract
Spin-cluster excitations induced by microwave radiation have been detected as a function of an applied magnetic field in the rare-earth kagome system Nd3Ga5SiO14. The results are interpreted using a Heisenberg model which allows for anisotropic exchange interactions between neighboring spins. At a microwave frequency of 120 GHz the conventional independent-ion electron spin resonance (ESR) spectrum, due to Zeeman splitting of the ground state …
