Abstract

No presente projeto serão investigados materiais compósitos de PMN-PT e PBN com ferritas de Níquel e Cobalto, com objetivo de observar o efeito magnetoelétrico, bem com determinar o acoplamento entre as fases ferroelétricas e ferromagnéticas. Será utilizada a técnica de suscetibilidade AC para identificar os efeitos magnetostrictivos nos compósitos, além das técnicas convencionais utilizadas para essa caracterização.
