      Dependence of exchange anisotropy and coercivity on the Fe–oxide structure in oxygen-passivated Fe nanoparticles  [Article]

      Prados, C.; Multigner, M.; Hernando, Antonio; Sánchez López, Juan Carlos; Fernández Camacho, Asunción; Conde Amiano, Clara Francisca; Conde Amiano, Alejandro (American Institute of Physics, 1999)
      Ultrafine Fe particles have been prepared by the inert gas condensation method and subsequently oxygen passivated. The as-obtained particles consist in an Fe core surrounded by an amorphous Fe-oxide surface layer. The ...

      Evidence of spin disorder at the surface–core interface of oxygen passivated Fe nanoparticles  [Article]

      Bianco, Lucia del; Hernando, A.; Multigner, M.; Prados, Clara; Sánchez López, Juan Carlos; Fernández, A.; Conde Amiano, Clara Francisca; Conde Amiano, Alejandro (AIP Publishing, 1998)
      Hysteresis, thermal dependence of magnetization, and coercivity of oxide coated ultrafine Fe particles prepared by inert gas condensation and oxygen passivation have been studied in the 5–300 K range. The results are ...
