Measurements and analysis of the upper critical field on an underdoped and overdoped compounds
D. H. N. Dias, E. V. L. de Mello, J. L. Gonzalez +6
The upper critical field is one of the many non conventional properties of high- cuprates. It is possible that the anomalies are due to the presence of in…
Nernst effect and Critical Field in Cuprate Superconductors
D. N. Dias, E. S. Caixeiro, E. V. L. de Mello
A series of recent experiments on the Nernst effect, upper critical field and enhanced diamagnetic magnetization by Wang et al (PRB 73, 024510), were interpreted as to…
Phase Separation and the Phase Diagram in Cuprates Superconductors
E. V. L. de Mello, D. H. N. Dias, Otton Teixeira da Silveira Filho
We show that the main features of the cuprates superconductors phase diagram can be derived considering the disorder as a key property of these materials. Our basic point is that t…
Phase Separation and the Dual Nature of the Electronic Structure in Cuprates
E. V. L. de Mello, D. H. N. Dias
The dual nature of the electronic structure of stripes in was characterized by experimental observations, mainly by ARPES, of nodal spectral weight together wit…
