有机分子的手性在化学、生物学和自旋电子学等领域引起了广泛的关注。本文报道了由超薄铁（001）、手性酞菁分子(（P)-或(M)- pbpc - dtbph）和氧化镁（001）组成的多层材料的垂直磁化磁滞回线。我们发现了一个手性相关的滞后环位移。与先前报道的偏置电流诱导现象不同，结果显示在系统中没有偏置电流的情况下，酞菁分子中存在手性诱导的有效磁场。本研究为新兴的手性分子自旋电子学领域开辟了新的方向。
Chirality in organic molecules has attracted considerable attention in the fields of chemistry, biology, and spintronics. This paper reports on perpendicular magnetization hysteresis loops of a multilayer consisting of ultrathin Fe (001), chiral phthalocyanine molecule ((P)- or (M)-PbPc-DTBPh), and MgO (001). We find a chirality-dependent shift of the hysteresis loop. Unlike the previously reported bias current induced phenomena, the result shows a chirality-induced effective magnetic field in the phthalocyanine molecule in the absence of a bias current in the system. This study opens up a new direction in the emerging field of chiral molecular spintronics.
