Abstract

The present Proposal is a continuation of the research in new materials involving high magnetic fields and low temperatures, object of the preceeding Projeto Temático (Proc. FAPESP n. 07/50968-0) ended in May 30th, 2014. The Laboratório de Novos Materiais Semicondutores (LNMS/DFMT/IFUSP) and the Laboratório de Estado Sólido e Baixas Temperaturas (LESBT) do Departamento de Física dos Materiais e Mecânica (DFMT) do Instituto de Física da USP is equiped with the infrastructure and techniques needed for the utilization of high fields and low temperatures, therefore being the main center where the experiments will be performed. The programs are as follows:- advanced materials (transport studies of topological insulators such as quantum wells of HgTe, and quantum transport studies in graphene);- semiconducting materials (transport studies in Bi2Te3 and IV-VI structures); - diluted magnetic oxides (electric and magnetic properties of ZnO, TiO2, SnO2 and CeO2)- frustrated magnetic materials (study of the properties of pyrochlore and spinnels mainly based on the Gd ion);- organic magnetic materials (mostly constituted by the radicals BImNN, MNPP e BABI);- magnetism and superconductivity (study of compounds based on FeAs);- magneto-electric effect (mainly in NiCl2.4SC(NH2)2 based compounds).Besides the group of the LNMS led by Prof. Gennady Gusev, two other groups participate directly in the project, namely the group of the the Laboratório de Estado Sólido e Baixas Temperaturas (LESBT) led by Prof. Valmir Chitta, and the group of Propriedades Óticas e Magnéticas dos Sólidos (GPOMS) of the Gleb Wataghin Institute of UNICAMP, led by Prof. Pascoal Pagliuso, and group de Fí-sica de Semicondutores do Intistuto de Física de São Carlos/USP led by Prof. Yury Pusep. Other collaborators are the Laboratório de Sensores e Materiais of the Instituto Nacional de Pesquisas Espaciais (LAS/INPE), led by Dr. Eduardo Abramov, and various other groups from abroad (Russia, USA and France).
