Voltage controlled interfacial magnetism through platinum orbits

摘要: Electric fields at interfaces exhibit useful phenomena, such as switching functions in transistors, through electron accumulations and/or electric dipole inductions. We find one potentially unique situation a metal–dielectric interface which the field is atomically inhomogeneous because of strong electrostatic screening effect metals. Such enable us to access quadrupoles shell. Here we show, by synchrotron X-ray absorption spectroscopy, induction magnetic moments platinum monatomic layer placed on ferromagnetic iron. Our theoretical analysis indicates that quadrupole produces and provides large anisotropy change. In contrast with inability current designs offer ultrahigh-density memory devices using electric-field-induced spin control, our findings material design showing more than ten times larger energy change for use highlight path electric-field control condensed matter. magnetization usually weak this hampers its application ultralow-power-consumption spintronic devices. Here, authors demonstrate mechanism enhance voltage-induced interface.
