论文摘要
我们通过旋转阀型三层型中的抗磁磁性间隔者观察到了两个铁磁层的强热控制镁介导的层间耦合。该效应表现为两种铁磁体的场引起的相干切换,可以通过变化的温度和间隔厚度来控制。我们将观察到的行为解释为由于在抗铁磁垫片的Néel温度以下的温度下,在三层中的铁和抗磁磁化模式的强杂交造成。
We observe a strong thermally-controlled magnon-mediated interlayer coupling of two ferromagnetic layers via an antiferromagnetic spacer in spin-valve type trilayers. The effect manifests itself as a field-induced coherent switching of the two ferromagnets, which can be controlled by varying temperature and the spacer thickness. We explain the observed behavior as due to a strong hybridization of the ferro- and antiferro-magnetic magnon modes in the trilayer at temperatures just below the Néel temperature of the antiferromagnetic spacer.
