Essential aspects of the spontaneous exchange bias effect
L. Bufaiçal, E. M. Bittar
Here, we present a review of the phenomenology of the spontaneous exchange bias effect, a phenomenon in which some materials exhibit unidirectional magnetic anisotropy even without…
Tuning the spontaneous exchange bias effect in La1.5Sr0.5CoMnO6 with sintering temperature
C. Macchiutti, J. R. Jesus, F. B. Carneiro +8
Here, we present a study of the influence of microstructure on the magnetic properties of polycrystalline samples of the La1.5Sr0.5CoMnO6 double perovskite, with primary attention…
The Co-Ir orbital hybridization in LaCaCoIrO double perovskite
L. Bufaiçal, L. S. I. Veiga, J. R. L. Mardegan +5
Here, we report on the structural, electronic, and magnetic properties of a polycrystalline sample of the LaCaCoIrO double-perovskite investigated by means of synchrotron x-ray…
Structural, electronic and magnetic properties of LaCa(CoFe)IrO double perovskite
L. Bufaiçal, M. A. V. Heringer, J. R. Jesus +4
In this work, we report the synthesis and investigation of structural, electronic, and magnetic properties of LaCa(CoFe)IrO. Our polycrystalline…
The spontaneous exchange bias effect in La2-xCaxCoMnO6 series
J. R. Jesus, L. Bufaiçal, E. M. Bittar
Structural, electronic and magnetic properties of polycrystalline La2-xCaxCoMnO6 (0 x 0.75) compounds are investigated by x-ray diffraction and magnetometry. All the…
Absence of zero-field-cooled exchange bias effect in single crystalline La2-xAxCoMnO6 (A = Ca, Sr) compounds
C. Macchiutti, J. R. Jesus, F. B. Carneiro +4
Magnetic properties of A2BB'O6 (A = rare or alkaline earth ions; B,B' = transition metal ions) double perovskites are of great interest due to their potential spintronic applicatio…
