Abstract
We study a dilute system of the isotropic classical Heisenberg spins coupled via the Ruderman-Kittel-Kasuya-Yosida interaction using a hybrid Monte Carlo spin-dynamics method. We find strong evidence of the occurrence of a spin-glass phase at finite, nonzero temperatures, contrary to previous predictions. We suggest that the spin-glass phase of this system can be characterized by a power-law decay of spin correlations.Keywords
