Griffiths phase and spontaneous exchange bias in LaSrCoMnFeO
A. G. Silva, K. L. Salcedo Rodríguez, C. P. Contreras Medrano +4
LaSrCoMnFeO (LSCMFO) compound was prepared by solid state reaction and its structural, electronic and magnetic properties were investigated. T…
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.…
The zero-field-cooled exchange bias effect in phase-segregated LaACoMnO (A = Ba, Ca, Sr; x = 0, 0.5)
L. T. Coutrim, D. Rigitano, C. Macchiutti +9
In the zero-field-cooled exchange bias (ZEB) effect the unidirectional magnetic anisotropy is set at low temperatures even when the system is cooled in the absence of external magn…
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…
