    • Cone magnetization state and exchange bias in IrMn/Cu/[Co/Pt]3 multilayers 

      Castro, Gustavo Montgomery Bonfim; Geshev, Julian Penkov; Schmidt, Joao Edgar; Baggio-Saitovitch, E.; Nagamine, Luiz Carlos Camargo Miranda (2009) [Journal article]
      The effects of a Cu interlayer on the perpendicular exchange bias in IrMn/Cu/[Co/ Pt]3 multilayers were investigated by focusing on the correlation between the exchange bias and the magnetic anisotropy. The in-plane ...
    • Effect of interface intermixing on giant magnetoresistance in NiFe/Cu and Co/NiFe/Co/Cu multilayers 

      Nagamine, Luiz Carlos Camargo Miranda; Biondo Filho, Armando; Pereira, Luis Gustavo; Silva, Alexandre Mello de Paula; Schmidt, Joao Edgar; Chimendes, Tiago Walescko; Cunha, Joao Batista Marimon da; Baggio-Saitovitch, E. (2003) [Journal article]
      This article reports on the important influence of the spontaneously built-in paramagnetic interfacial layers on the magnetic and magnetoresistive properties of NiFe/Cu and Co/NiFe/Co/Cu multilayers grown by magnetron ...
    • Energy deposition of H and He ion beams in hydroxyapatite films : a study with implications for ion-beam cancer therapy 

      Limandri, Silvina P.; de Vera Gomis, Pablo; Fadanelli Filho, Raul Carlos; Nagamine, Luiz Carlos Camargo Miranda; Silva, Alexandre Mello de Paula; García-Molina, Rafael; Behar, Moni; Abril Sanches, Isabel (2014) [Journal article]
      Ion-beam cancer therapy is a promising technique to treat deep-seated tumors; however, for an accurate treatment planning, the energy deposition by the ions must be well known both in soft and hard human tissues. Although ...
    • Energy loss of proton, [alpha] particle, and electron beams in hafnium dioxide films 

      Behar, Moni; Fadanelli Filho, Raul Carlos; Abril Sanches, Isabel; García-Molina, Rafael; Denton, Cristian D.; Nagamine, Luiz Carlos Camargo Miranda; Arista, Nestor (2009) [Journal article]
      The electronic stopping power, S, of HfO₂ films for proton and alpha particle beams has been measured and calculated. The experimental data have been obtained by the Rutherford backscattering technique and cover the range ...
    • Exchange bias through a Cu interlayer in an IrMn/Co system 

      Geshev, Julian Penkov; Nicolodi, Sabrina; Pereira, Luis Gustavo; Nagamine, Luiz Carlos Camargo Miranda; Schmidt, Joao Edgar; Deranlot, Cyrile; Petroff, Frédéric; Rodríguez-Suárez, Roberto Lazaro; Costa, Antonio Azevedo da (2007) [Journal article]
      Ferromagnetic resonance FMR and magnetization MAG measurements were used to study the exchange interaction between the antiferromagnetic and ferromagnetic layers in an IrMn/Cu/Co system as a function of the Cu spacer ...
    • Frequency-dependent exchange bias in NiFe/NiO films 

      Geshev, Julian Penkov; Pereira, Luis Gustavo; Schmidt, Joao Edgar; Nagamine, Luiz Carlos Camargo Miranda; Baggio-Saitovitch, E.; Pelegrini, Fernando (2003) [Journal article]
      Ferromagnetic (FM) resonance and magnetization curve measurements were performed at room temperature for a polycrystalline Ni81Fe19 coupled to NiO. It was observed that the shape of the angular variation of the resonance ...
