      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 ...

      Magnetic and microstructural analysis of palladium nanoparticles with different capping systems  [Article]

      Litrán Ramos, Rocío; Sampedro, Blanca; Rojas Ruiz, Teresa Cristina; Multigner, Marta; Sánchez López, Juan Carlos; Crespo, Patricia; López Cartes, Carlos; García García, Miguel Ángel; Hernando, Antonio; Fernández Camacho, Asunción (American Physical Society, 2006)
      Palladium nanoparticles capped with different protective systems in a size range between 1.2 and 2.4 nm have been obtained by varying the preparation chemical method. Magnetization curves for all the samples show hysteresis ...

      Magnetometry and electron paramagnetic resonance studies of phosphine- and thiol-capped gold nanoparticles  [Article]

      Guerrero, Estefanía; Muñoz Márquez, Miguel Ángel; Fernández Camacho, Asunción; Crespo, P.; Hernando, Antonio; Lucena, R.; Conesa Cegarra, José Carlos (American Institute of Physics, 2010)
      In the last years, the number of studies performed by wholly independent research groups that confirm the permanent magnetism, first observed in our research lab, for thiol-capped Au nanoparticles (NPs) has rapidly increased. ...
