摘要

摘要报道了尖晶石结构的Pt和磁性绝缘体mgfe2o4 (MFO)双层层的自旋霍尔磁阻(SMR)。Pt厚度对SMR的影响表明，在沉积Pt层之前，MFO表面的退火对于具有良好界面质量的大型SMR至关重要。我们还发现生长过程中的氧气压力对SMR几乎没有影响，但会影响MFO膜的磁性能。我们的发现为进一步理解含磁绝缘体界面的自旋输运提供了重要线索，促进了低功耗器件的开发。

Effect of interface quality on spin Hall magnetoresistance in Pt/MgFe₂O₄ bilayers

Abstract We report on spin Hall magnetoresistance (SMR) in bilayers composed of Pt and magnetic insulator MgFe 2 O 4 (MFO) with spinel structure. The Pt thickness dependence of the SMR reveals that annealing of the MFO surface before depositing the Pt layer is crucial for a large SMR with better interface quality. We also found that oxygen pressure during the MFO growth hardly affects the SMR while it influences on magnetic property of the MFO film. Our findings provide important clues to further understand the spin transport at interfaces containing magnetic insulators, facilitating development of low power consumption devices.
