Efeitos de campos magnéticos aleatórios em sistemas de vidro de spin com clusters
(Universidade Federal de Santa Maria, 2019-03-08)
This work investigates the effects of the presence of random magnetic fields (RFs) in
thermodynamic quantities that characterize the spin glass state (VS). We adopt a cluster
spin model that considers long-range disordered ...
