A stretched exponential-based approach for the magnetic properties of spin glasses
Leandro Bufaiçal
The spin glasses show intriguing characteristic features that are not well understood yet, as for instance its aging, rejuvenation and memory effects. Here a model based on a stret…
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…
