Abstract :
This paper discusses the appearance of the non-collinear spin structure in the ferromagnetic/antiferromagnetic (FM/AFM) bilayer system with the Ll2-type ordered AFM alloy. The model is within the framework of the classical Heisenberg model. The FM spin show the shifted magnetization loop under the influence of the exchange bias. The uncompensated spin element in the AFM layer shows the hysteresis loop and also indicates the biasing shift. That biasing field in the AFM layer is equivalent to the bias in the FM layer.
