Correlation between the magnetic irreversibility limit and the zero resistance point in different granular YBa/sub 2/Cu/sub 3/O/sub 7-σ superconductors
Dias, Fabio Teixeira; Vieira, Valdemar das Neves; Rodrigues Junior, Pedro; Obradors, Xavier; Pureur Neto, Paulo; Schaf, Jacob (2008) [Artículo de periódico]We report on magnetization and magnetoresistance measurements of single-crystal, melt-processed, and polycrystalline YBa2Cu3O7− samples with the purpose of disclosing the connection between the magnetic irreversibility ... -
Paramagnetic effect at low and high magnetic fields in melt-textured YBa/sub 2/Cu/sub 3/O/sub 7-[delta]/
Dias, Fabio Teixeira; Pureur Neto, Paulo; Rodrigues Junior, Pedro; Obradors, Xavier (2004) [Artículo de periódico]We report on systematic field-cooled magnetization experiments in five different melt-textured YBa2Cu3O7 samples containing large amounts of Y2BaCuO5 precipitates. These composites were grown with the Bridgman or top-seeding ...
