Modos massivos e paredes de domínio em líquidos de Fermi
(Universidade Federal de São Carlos, 2018-06-11)
In this thesis, we use Fermi liquid theory to deal with three problems. The first and second problems are about a direct and an indirect detection of the amplitude massive ‘‘Higgs’’ mode in weak ferromagnets like ZrZand M ...
Propriedades magnéticas de BiMn2O5 e Fe3O2BO3
(Universidade Federal de São Carlos, 2018-02-26)
In this work, an exploration of the synthesis and magnetoelectric properties of single-crystals of BiMn2O5 and a systematic study of the magnetic properties of Fe3O2BO3 are presented. Despite the unlike composition, both ...
