      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

      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 ...
