One-pot synthesis: a simple and fast method to obtain ceramic superconducting materials

Maycon Rotta, Maycon Motta, Alexsander L Pessoa +5

The one-pot method focuses on the reduction of the number of steps or chemical reactions in the synthesis of materials, and it is very appealing in terms of sustainability. In addi…

Vortices in a mesoscopic superconducting circular sector

Edson Sardella, Paulo Noronha Lisboa-Filho, Andre Luiz Malvezzi

In the present paper we develop an algorithm to solve the time dependent Ginzburg-Landau (TDGL) equations, by using the link variables technique, for circular geometries. In additi…

Vortices in superconductors with a columnar defect: finite size effects

Edson Sardella, Rodrigo de Alvarenga Freire, P. N. Lisboa-Filho

In the present work we investigate the behavior of a vortex in a long superconducting cylinder near to a columnar defect at the center. The derivations of the local magnetic field…

Study of magnetic and specific heat measurements at low temperatures in Nd0.5Sr0.5MnO3 and Nd0.5Ca0.5MnO3

J. Lopez, P. N. Lisboa-Filho, O. F. de Lima +1

The magnetization at low temperatures for Nd0.5Sr0.5MnO3 and Nd0.5Ca0.5MnO3 samples showed a rapid increase with decreasing temperatures, contrary to a La0.5Ca0.5MnO3 sample. Speci…
