在具有红外隧穿磁电阻的Co-Al-O金属-绝缘体颗粒磁性薄膜中观察到了磁折射效应，即磁化后反射率的变化。结果表明，这种效应在干涉条件下表现得最明显，在磁化强度上是均匀的，在频率约为1100 cm-时高达0.8%，超过了线性赤道克尔效应和均匀取向磁光效应一个数量级。
The magnetorefractive effect, consisting in a change of reflectivity under magnetization, has been observed in granular Co-Al-O metal-insulator magnetic films with tunneling magnetoresistance in the IR region. It is shown that this effect manifests itself most clearly in interference conditions, is even in magnetization, and reaches as high as 0.8% at frequencies of about 1100 cm−, which exceeds both the linear equatorial Kerr and the even orientational magneto-optic effects by an order of magnitude.
