    • Comparison of empirical interatomic potentials for iron applied to radiation damage studies 

      Becquart, C.S.; Willaime, F.; Terentyev, Dimitry; Serra Tort, Ana María; Nordlund, K.; Malerba, L.; Marinica, M.C.; Anento Moreno, Napoleón; Björkas, C.; Nguyen, H.; Domain, C.; Djurabekova, F.; Olsson, P. (2010)

      Accés restringit per política de l'editorial
      The performance of four recent semi-empirical interatomic potentials for iron, developed or used within the FP6 Perfect Project, is evaluated by comparing them between themselves and with available experimental or, more ...

    • Effect of the incorporation of BiFeO3 on the structural, electrical and magnetic properties of the lead-free Bi0.5Na0.5TiO3 

      Zuñiga-Mera, Pablo W; Gaona Jurado, Sonia; Guerrero, Alejandra Isabel; Villaquirán Raigoza, Claudia Fernanda; García García, José Eduardo (2021-11-05)
      Article
      Accés obert
      Powders of the system (1–x)Bi0.5Na0.5TiO3–xBiFeO3 (x = 0, 0.02, 0.08, 0.10) are synthesized by the combustion reaction method. The crystal structure and the particle size of Bi0.5Na0.5TiO3 are modified by the incorporation ...

    • Ferromagnetic transition of a two-component Fermi gas of hard spheres 

      Arias de Saavedra, F.; Mazzanti Castrillejo, Fernando Pablo; Boronat Medico, Jordi; Polls, A. (2012-03-12)
      Article
      Accés obert
      We use microscopic many-body theory to analyze the problem of itinerant ferromagnetism in a repulsive atomic Fermi gas of hard spheres. Using simple arguments we show that the available theoretical predictions for the onset ...

    • Magnetoelectric response in (1-x)PbZr0.65Ti0.35O3-xBaFe(12)O(19) multiferroic ceramic composites 

      Guerra, Jose D. S.; Betal, Soutik; Pal, Madhuparna; García García, José Eduardo; Oliveira, Adilson J. A; M'Peko, Jean-Claude; Hernandes, Antonio Carlos; Guo, Ruyan; Bhalla, Amar S. (2015-05-01)
      Article
      Accés obert
      The magnetoelectric (ME) properties of PbZr0.65Ti0.35O3-BaFe12O19 (PZT-BaM) multiferroic ceramic composites have been investigated in this work. These materials, containing both the ferroelectric PZT and ferrimagnetic BaM ...

    • Modelling shape-memory effects in ferromagnetic alloys 

      Gebbia, Jonathan Fernando; Lloveras Muntané, Pol Marcel; Planes Vila, Antoni; Castán Vidal, Teresa; Saxena, Avadh (Springer, 2015-07-21)
      Article
      Accés restringit per política de l'editorial
      We develop a combined Ginzburg–Landau/micromagnetic model dealing with conventional and magnetic shape-memory properties in ferromagnetic shape-memory materials. The free energy of the system is written as the sum of ...

    • Poly(Dimethylsiloxane) Magnetically-actuated Variable Optical Attenuator 

      Pedro Joan, Sandra de (Universitat Politècnica de Catalunya, 2009-09-09)
      Projecte Final de Màster Oficial
      Accés obert
      The idea of mixing optical and magnetic properties in an only device has been the seed of this MSc Thesis. As a result of all the work done a Magneticallyactuated Variable Optical Attenuator (M-VOA) has been developed. ...
