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…
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…
