Orbital localization and the role of the Fe and As orbitals in BaFeAs probed by XANES
A. G. de Figueiredo, M. R. Cantarino, W. R. da Silva Neto +9
The polarization dependence of the near edge x-ray absorption spectroscopy (XANES) is an element specific probe to the real-space distribution of the density of unoccupied states i…
A phenomenological model for the spontaneous exchange bias effect
L. Bufaiçal, L. T. Coutrim, E. M. Bittar +1
In this work we propose an alternative model to explain the spontaneous exchange bias (SEB) effect observed in spin glass (SG)-like systems. As in a previously proposed model (Ref.…
Influence of spin glass-like magnetic relaxation on the zero-field-cooled exchange bias effect
L. T. Coutrim, E. M. Bittar, F. Garcia +1
The zero-field-cooled exchange bias (ZEB) effect is a remarkable phenomenon recently reported for some reentrant spin glass-like compounds. In this work, the time-evolution of magn…
Dynamic magnetism in the disordered hexagonal double perovskite BaTiMnO
M. R. Cantarino, R. P. Amaral, R. S. Freitas +10
Magnetic frustration and disorder are key ingredients to prevent the onset of magnetic order. In the disordered hexagonal double perovskite BaTiMnO, Mn…
Compensation temperatures and exchange bias in La1.5Ca0.5CoIrO6
L. T. Coutrim, E. M. Bittar, F. Stavale +8
We report on the study of magnetic properties of the La1.5Ca0.5CoIrO6 double perovskite. Via ac magnetic susceptibility we have observed evidence of weak ferromagnetism and reentra…
Direct determination of the crystal field parameters of Dy, Er and Yb impurities in the skutterudite compound CeFeP by Electron Spin Resonance
D. J. Garcia, F. A. Garcia, J. G. S. Duque +5
Despite extensive research on the skutterudites for the last decade, their electric crystalline field ground state is still a matter of controversy. We show that Electron Spin Reso…
