    • 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) [Artículo de periódico]
      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) [Artículo de periódico]
      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 ...

    • 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) [Artículo de periódico]
      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 ...

    • Isomer shift and electronegativy in compounds of tin and group -VI elements 

      Baggio-Saitovitch, E.; Sonnino, Tullio (1970) [Artículo de periódico]
      Using the Mössbauer effect in 119Sn we have measured the isomer shift in compounds of divalent and tetravalent tin with elements of Group VI. The isomer shift is linearly dependent on the values of electronegativity in ...

    • Magnetotransport properties in the magnetic phase of BaFe2−xTxAs2 (T = Co,Ni) : a magnetic excitations approach 

      Peña Pacheco, Jully Paola; Piva, M. M.; Rosa, P. F. S.; Pagliuso, P. G.; Adriano, C.; Grant, Ted W.; Fisk, Zachary; Baggio-Saitovitch, E.; Pureur Neto, Paulo (2018) [Artículo de periódico]
      Because of their complex Fermi surfaces, the identification of the physical phenomena contributing to electronic scattering in the Fe-based superconductors is a difficult task. Here, we report on the electrical resistivity, ...

    • Phase diagram of the heavy fermion system YbFe/sub 2/Ge/sub 2/ under pressure 

      Larrea Jiménez, Julio Antonio; Fontes, Magda Bittencourt; Baggio-Saitovitch, E.; Plessel, Jochen; Abd-Elmeguid, Mohsen M.; Ferstl, Julia; Geibel, Christoph; Pereira, Altair Soria; Jornada, Joao Alziro Herz da; Continentino, Mucio Amado (2006) [Artículo de periódico]
      The phase diagram of the heavy fermion compound YbFe2Ge2 under high pressures P ≤ 18.2 GPa was obtained by electrical resistivity measurements. Pressure drives the system from a paramagnetic Fermi liquid state to a ...

    • Spin texture on top of flux avalanches in Nb/Al2O3/Co thin film heterostructures 

      Lopes, Rovan Fernandes; Carmo, Danusa do; Colauto, Fabiano; Ortiz, Wilson Aires; Andrade, Antonio Marcos Helgueira de; Johansen, Tom Henning; Baggio-Saitovitch, E.; Pureur Neto, Paulo (2017) [Artículo de periódico]
      We report on magneto-optical imaging, magnetization, Hall effect, and magneto-resistance experiments in Nb/Al2O3/Co thin film heterostructures. The magneto-transport measurements were performed in samples where electrical ...
