论文摘要
我们通过使用薄饼探测器条通过热产生的非局部木元传输来介绍抗磁磁性范德华材料MNPS3中自旋流动过渡的检测。反异常的自旋霍尔效应具有独特的能力来检测平面外旋转积累,这使我们能够以平面外旋转极化来检测镁质。与仅具有自旋霍尔效应的高自旋轨道材料(例如PT)的条形,并且仅对自旋积累的平面自旋极化敏感。我们表明,在没有其他伪造效应的情况下,非局部木吞传输能够测量自旋流动过渡。我们的测量结果表明,在自旋触发过渡之前和之后,旋转seebeck效应产生的镁的检测,其中镁自旋积累的信号反转与SF过渡之前和之后由镁模式携带的OOP自旋极化一致。
We present the detection of the spin-flop transition in the antiferromagnetic van der Waals material MnPS3 via thermally generated nonlocal magnon transport using permalloy detector strips. The inverse anomalous spin Hall effect has the unique power to detect an out-of-plane spin accumulation which enables us to detect magnons with an out-of-plane spin polarization; in contrast to strips of high spin-orbit material such as Pt which only possess the spin Hall effect and are only sensitive to an in-plane spin polarization of the spin accumulation. We show that nonlocal magnon transport is able to measure the spin-flop transition in the absence of other spurious effects. Our measurements show the detection of magnons generated by the spin Seebeck effect before and after the spin-flop transition where the signal reversal of the magnon spin accumulation agrees with the OOP spin polarization carried by magnon modes before and after the SF transition.
