我们已经开发出一种纳米纤维技术，以促进电流垂直于平面的磁性多层柱结构的直径为100 nm的尺寸尺度，在该尺寸尺度上的铁磁层内的各个域的反转可以被检测到的传输测量。当大电流通过这样的柱时，由电流产生的奥斯特场可以影响层的磁矩的取向。在250至500 nm范围内的柱中，交替的硬和软铁磁层的堆叠可以经由该机制在高电阻状态和低电阻状态之间可控地切换。
We have developed a nanofabrication technique to facilitate current-perpendicular-to-plane transport measurements on magnetic multilayer pillar structures with diameters as narrow as 100 nm—a size scale at which the reversal of individual domains within the ferromagnetic layers may be detected. When large currents are passed through such pillars, the Oersted field produced by the current can affect the orientation of the magnetic moments of the layers. In pillars ranging from 250 to 500 nm, a stack of alternating hard and soft ferromagnetic layers can controllably be switched between high and low resistance states via this mechanism.
