%A Costa, Giancarlo Cordeiro %A Azevedo Neves, Marcelo %A Souza Pereira, Agnaldo %D 2014 %T A NEW METHOD FOR NON DESTRUCTIVE ESTIMATION OF Jc IN YBaCuO CERAMIC SAMPLES %K %X This work presents a new method for estimation of Jc as a bulk characteristic of YBCO blocks. The experimental magnetic interaction force between a SmCo permanent magnet and a YBCO block was compared to finite element method (FEM) simulations results, allowing us to search a best fitting value to the critical current of the superconducting sample. As FEM simulations were based on Bean model , the critical current density was taken as an unknown parameter. This is a non destructive estimation method. since there is no need of breaking even a little piece of the sample for analysis. %U http://www.uezo.rj.gov.br/ojs/index.php/ast/article/view/61 %J Acta Scientiae et Technicae %0 Journal Article %R 10.17648/uezo-ast-v2i2.61 %V 2 %N 2 %@ 2317-8957 %8 2014-12-01
