Effects of holmium substitution on multiferroic properties in Tb0.67Ho0.33MnO3

M. Staruch, G. Lawes, A. Kumarasiri, Luiz F. Cotica e M. Jain

APPLIED PHYSICS LETTERS – Volume: 102; Issue: 6; Article Number: 062908; DOI: 10.1063/1.4792526

In this work, the structural, electrical, and magnetic properties of orthorhombic TbMnO3 and Tb0.67Ho0.33MnO3 ceramics are presented. The lattice parameters and the Mn-O-Mn bond angle were found to decrease with Ho-substitution as […]

Propriedades Eletro-Ópticas e de Interfaces em Cristais Líquidos Nemáticos Quirais para Aplicações em Displays

Início: 01/10/2013
Término:

Equipe: Deng-Ke Yang, Ervin Kaminski Lenzi, Luiz Roberto Evangelista, Rafael Soares Zola (coordenador), Roberto Rossato e Veridiana Garcia Guimarães

A fase liquido cristalina nemática quiral, também conhecida como colestérica tem grande potencial para aplicações tecnológicas,como displays. Embora o Brasil tenha diversos grupos que se dediquem a estudar cristais líquidos, poucos se empenham no desenvolvimento de displays, focando exclusivamente a física básica […]

Electrical current profile of a confined isotropic liquid sample: Biological systems and liquid crystals applications

Roberta R. Ribeiro de Almeida, Flávio S. Michels, V. Steffen, Ervin K. Lenzi, Rafael S. Zola e Luiz R. Evangelista
