| 摘 要： | 采用Monte Carlo 方法,研究铁磁/反铁磁双层膜中的磁锻炼效应.结果表明,反铁磁层中冷场诱发的界面净磁化(钉扎效应)的磁弛豫可导致系统中的交换偏置场的磁锻炼效应.进一步研究表明,反铁磁层中掺杂可调控交换偏置场的磁锻炼效应,原因在于反铁磁层中掺杂能有效地改变冷场诱发的净磁化的磁弛豫过程.

| Abstract: | Using Monte Carlo method to study the magnetic training effect in the ferromagnetic/antiferromagnetic bilayers, it was shown that the magnetic relaxation of the net magnetization induced by cold magnetic field which exists in the interface between ferromagnetic and antiferromagnetic bilayer can result in the training effect in the exchange bias and coercivity of the system. Further studies have shown that the doping in antiferromagnetic layer can modulate the training effect in the exchange bias, because the doping in antiferromagnetic layer can effectively change the magnetic relaxation process of the net magnetization induced by the cold field. |
