Em primeiro momento, agradeço de um modo geral a todos e a tudo que de certa forma contribuiu para a realização desta obra e para a minha formação profissional e pessoal. À Deus por todo o mistério da vida e causador da incessante busca pela verdade. Ao Prof. Dr. Laudemir Carlos Varanda pelos valiosos ensinamentos e discussões que contribuíram para a minha formação profissional e intelectual. Aos amigos do grupo de materiais coloidais que convivi durante o mestrado:
SmCo, face centered tetragonal phase (fct) FePt and CoC nanomaterials have been studied for application in magnetic recording and permanent magnets due to theirs high coercivity and magnetocrystalline anisotropy. One-dimensional FePt nanoparticles were proposed to improve the magnetic alignment of selfassembled system. In this work, the formation of FePt nanorods and nanowires was studied by using a small amount of carbon monoxide from the precursor pentacarbonyliron(0) and oleylamine. Both parameters of synthesis were studied and was verified that they influence the one-dimensional growth of FePt. In fact,
