  Estudo do Efeito Magnetocalórico em sistemas intermetálicos das terras-raras, Descrição: A refrigeração usando materiais sólidos é baseada na variação da temperatura e da entropia do material, controlada pela variação de um agente externo (campo magnético, campo elétrico, pressão, etc.). Quando a variação de temperatura do material ocorre devido a uma variação do campo magnético teremos o efeito magnetocalórico; os efeitos eletrocalórico e barocalórico ocorrem quando variamos o campo elétrico e a pressão, respectivamente. O processo de maior destaque na literatura científica de refrigeração usando materiais sólidos faz uso do efeito magnetocalórico. A refrigeração magnética tem uma grande vantagem de natureza ecológica, elimina o uso de clorofluorcarbetos (CFC) e hydrofluorcarbetos (HCFCs) no processo de resfriamento. Além da eliminação dos poluentes, a refrigeração magnética poderá ser produzida com menor perda de energia. Nesse projeto cinco linhas de investigações serão desenvolvidas: 1] Estudo do efeito magnetocalórico com aplicação na série Gd(1-x)DyxAl2; 2] Investigação do efeito magnetocalórico anisotrópico nos compostos da série Er(1-x)Tb(x)Al2; 3] Estudo das propriedades magnéticas e magnetocalóricas em compostos magnéticos amorfos; 4] Estudo da influencia da histerese nos efeitos barocalórico e magnetocalórico, com aplicação ao composto Gd5Si2Ge2; 5] Estudo do efeito magnetocalórico nos compostos da série Gd1-xCexAl2. As metas principais desse projeto são: (a) construções de modelos teóricos para descrever os efeitos magnetocalórico e barocalórico em sistemas magnéticos com fortes anisotropias de campo elétrico cristalino; (b) investigar o efeito magnetocalórico anisotrópico; (c) Investigar a capacidade de refrigeração em sistemas magnéticos amorfos e comparar com os sistemas magnéticos cristalinos; (d) entender e minimizar a influencia das histereses térmicas e magnéticas no efeito magnetocalórico e barocalórico; (f) Investigar a influencia da mudança no ordenamento magnético (ferromagnético?antiferromagnético) no efeito magnetocalórico.. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (1) / Mestrado acadêmico: (2) / Doutorado: (2) . , Integrantes: Pedro Jorge von Ranke Perlingeiro - Integrante / Pedro Jorge von Ranke - Coordenador / A Caldas - Integrante / Vinicius R Sounsa - Integrante / de Oliveira, N A - Integrante / Alho, B P - Integrante / Nóbrega, E.P. - Integrante.
