    • Computation of critical current in artificially structurated bulk samples from Hall measurements 

      Carrera, Miquel; Granados García, Xavier; Amorós Torrent, Jaume; Maynou Gil, Roger; Puig Molina, Teresa; Obradors Berenguer, Xavier (Institute of Physics (IOP), 2008)
      Article
      Accés obert
      High-temperature superconducting artificially structured bulk samples, such as bulks with slanted drills or welds of different pieces along the c-axis with holes drilled in different asymmetric positions, ...

    • Current distribution in HTSC tapes obtained by inverse problem calculation 

      Carrera, Miquel; Granados García, Xavier; Amorós Torrent, Jaume; Maynou Gil, Roger; Puig Molina, Teresa; Obradors Berenguer, Xavier (Institute of Physics (IOP), 2010)
      Article
      Accés obert
      The development of SC devices based on HTSC tapes requires a deep knowledge of the current distribution in both pre-saturation and post-saturation regimes. Magnetic measurements have shown the possibilities ...

    • Current distributions in wide YBCO tapes 

      Carrera, Miquel; Granados García, Xavier; Amorós Torrent, Jaume; Puig Molina, Teresa; Obradors Berenguer, Xavier (Elsevier, 2012)
      Article
      Accés obert
      The need of a better mechanical behaviour and the stabilization of coated conductors for applications, as Magnets, cables or Fault Current Limiters, has motivated the lamination of tapes with stainless steel or copper ...

    • Fabrication of melt-textured cylinders and bars of (YBa2Cu3O7-Y2BaCuO5) superconductors 

      Piñol Vidal, Salvador; Yu, R; Vilalta, Nuria; Sandiumenge, Felip; Gomis Arbonès, Vicente; Martínez, Benjamín; Mora Serrano, Javier; Fontcuberta, Josep; Obradors Berenguer, Xavier (1996)
      Comunicació de congrés
      Accés restringit per decisió de l'autor
      Cylinders and bars of bulk YBa2CuO7-Y2BaCuO5 textured ceramic composites (123-211) have been prepared through different directional solidification processes. Green ceramic preforms for the directional solidification process ...

    • Functional behaviour of the anomalous magnetic relaxation observed in melt-textured YBCO samples showing the paramagnetic Meissner effect 

      Teixeira Dias, Fábio; Vieira, Valdemar das Neves; Garcia, E.L.; Wolff-Fabris, Frederik; Kampert, Erik; Paiva Gouvêa, Cristol de; Schaf, Jacob; Obradors Berenguer, Xavier; Puig, Teresa; Roa Rovira, Joan Josep (2016)
      Article
      Accés obert
      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
      Accés obert
      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 ...

    • Hysteresis motor with self sustained rotor for high speed applications 

      Granados García, Javier A.J.; Márquez, Isabel; Mora Serrano, Javier; Fontcuberta, Josep; Obradors Berenguer, Xavier; Pallarés, J.; Bosch Tous, Ricardo (Institute of Physics (IOP), 1997)
      Text en actes de congrés
      Accés obert
      Pellets of YBCO HTSC have been used to construct a cylindrically shaped rotor. A four poles/four phases stator has been wound in order to build a motor. The motor behaves as an hysteresis motor when it starts and as ...

    • Preparation of top seeded YBa2Cu3O7 large single-domain tiles 

      Yu, R; Gomis Arbonès, Vicente; Piñol Vidal, Salvador; Sandiumenge, Felip; Mora Serrano, Javier; Carrera, Miquel; Fontcuberta, Josep; Obradors Berenguer, Xavier (1997)

      Accés restringit per decisió de l'autor
      Single domain superconductors with diameters up to 40 mm have been prepared by top seeding growth using Nd123 melt textured ceramics as seeds. We show that the use of these seeds is preferred over MgO single crystals to ...
