      Open Access
      We have studied the functional behavior of the field-cooled (FC) magnetic relaxation observed in melt- textured YBa 2 Cu 3 O 7- d(Y123) samples with 30 wt% of Y 2 Ba 1 Cu 1 O 5 (Y211) phase, in order to investigate anomalous ...
    • High-field paramagnetic Meissner effect up to 14 T in melt-textured YBa2Cu3O7-delta 

      Teixeira Dias, Fábio; Vieira, Valdemar das Neves; Wolff-Fabris, Frederik; Kampert, Erik; Paiva Gouvêa, Cristol de; Campos, A.P.C.; Archanjo, B.S.; Schaf, Jacob; Obradors Berenguer, Xavier; Puig, T.; Roa Rovira, Joan Josep; Sahoo, B.K. (2016-06-01)
      Article
      Open Access
      We have performed magnetization experiments in a melt-textured YBa2Cu3O7-delta(Y123) sample with Y2BaCuO5 (Y211) inclusions, under magnetic fields up to 14 T applied parallel or perpendicular to the ab plane. Magnetic ...
    • Paramagnetic moments and time effects in melt-textured NdBaCuO system with Nd422 inclusions 

      Teixeira Dias, Fábio; Vieira, Valdemar das Neves; D. L., Silva; Wolff-Fabris, Frederik; Kampert, Erik; Almeida, M.L.; Mesquita, F; Hneda, M; Roa Rovira, Joan Josep (Institute of Physics (IOP), 2015)
      Article
      Open Access
      We have performed magnetic measurements in two melt-textured NdBa2Cu3O7-d samples with Nd422 inclusions under magnetic fields from 0.05 up to 14 T, applied parallel to the ab planes. The measurements were made with a ...
