  • Effect of minor Co additions on the crystallization and magnetic properties of Fe(Co)NbBCu alloys 

    Torrens Serra, Joan; Bruna Escuer, Pere; Roth, Segmar; Rodríguez Viejo, Javier; Clavaguera Mora, Maria Teresa (2010)
    Open Access
    The effect of partial replacement of Fe by Co (up to 8 %) on thermal stability, structure and magnetic properties of FeNbBCu alloys has been explored in this paper. The results indicate that Co reduces the stability against ...
  • Electron spin resonance on single-walled carbon nanotubes obtained from different sources 

    Ferrer Anglada, Núria; Abiad Monge, Aida; Roth, Segmar (2010-12)
    Restricted access - publisher's policy
    Weused electron spin resonance (ESR) to analyze several kinds of single-walled carbon nanotubes (SWNTs) synthesized by different methods. We observed that ESR is a sensitive probe that can be used to observe major differences ...
  • Flexible, transparent electrodes using carbon nanotubes 

    Ferrer Anglada, Núria; Iqbal, Muhammad Zahir; Pérez Puigdemont, Jordi; Figueras, Jordi; Roth, Segmar (2012-12-10)
    Open Access
    We prepare thin single-walled carbon nanotube networks on a transparent and flexible substrate with different densities, using a very simple spray method. We measure the electric impedance at different frequencies Z(f) in ...
  • Single-walled carbon nanotubes characterization by Electron Spin Resonance spectroscopy 

    Abiad Monge, Aida; Pérez Puigdemont, Jordi; Ferrer Anglada, Núria; Roth, Segmar (2010)
    Conference report
    Restricted access - confidentiality agreement
    Carbon nanotubes (CNTs) are interesting candidates for the development of new electronic devices and sensors due to their small size and their mechanical, optical and electrical properties [1-6]. Well-characterized ...
