Abstract 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 [1] , it is based on the unconventional dynamics of the SG-like moments at the magnetic hysteresis cycle. However, using a reliable estimate of the amount of SG-spins that are relaxing during the cycle, the new model can correctly describe the changes in the SEB observed for measurements performed at different…

Griffiths phase and spontaneous exchange bias in La1.5Sr0.5CoMn0.5Fe0.5O6.
The unidirectional anisotropy observed for LSCMFO is discussed and compared with those of resembling double-perovskite compounds, being plausibly explained in terms of its structural and electronic properties.
The Spontaneous Exchange Bias Effect on La1.5Ba0.5CoMnO6

Large exchange bias after zero-field cooling from an unmagnetized state.
An unusual phenomenon in which a large EB can be observed in Ni-Mn-In bulk alloys after zero-field cooling from an unmagnetized state is reported, and it is proposed that this is related to the newly formed interface between different magnetic phases during the initial magnetization process.
