  • CEMs and Faraday rotation study of ¿-Fe2O3- Fe3O4films obtained by a new pyrolisis technique 

    Cusidó Fàbregas, Joan Antoni; Obradors Berenguer, Xavier; Fontcuberta, Josep; Isalgue Buxeda, Antonio; Canal Bienzobas, Fernando; Joubert, Jean C.; Langlet, M. (1987-01)
    Article
    Open Access
    Thin film iron oxides prepared by a new pyrolisis technique are studied by means of CEM spectroscopy and Faraday rotation measurements. It is shown that Fe3O4spinel oxides are obtained when the deposition is performed under ...
  • 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)

    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 ...
  • Hysteresis motor with self sustained rotor for high speed applications 

    Granados García, Xavier; Márquez, Isabel; Mora Serrano, Javier; Fontcuberta, Josep; Obradors Berenguer, Xavier; Pallarés, J.; Bosch Tous, Ricardo (Institute of Physics (IOP), 1997)
    Conference report
    Open Access
    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)
    Conference lecture
    Restricted access - author's decision
    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 ...
