用MuMax3模拟补偿反铁磁界面

Modelling compensated antiferromagnetic interfaces with MuMax3

Jonas De Clercq, Jonathan Leliaert, Bartel Van Waeyenberge

摘要:

我们展示了如何补偿反铁磁自旋可以实现在微磁模拟程序MuMax 3。我们证明,我们可以模拟自旋翻转耦合作为一个单轴各向异性的小倾斜角,以及我们如何可以考虑到铁磁体和补偿反铁磁体之间的强耦合的确切能量项。我们还研究了双轴反铁磁体的训练效应,并在多晶IrMn/CoFe双层膜中再现了训练效应。

英文摘要:

We show how compensated antiferromagnetic spins can be implemented in the micromagnetic simulation program MuMax3. We demonstrate that we can model spin flop coupling as a uniaxial anisotropy for small canting angles and how we can take into account the exact energy terms for strong coupling between a ferromagnet and compensated antiferromagnet. We also investigate the training effect in biaxial antiferromagnets and reproduce the training effect in a polycrystalline IrMn/CoFe bilayer.
