Abstract

In thin-film ferromagnets with perfect easy-plane anisotropy, the component of total spin perpendicular to the easy plane is a good quantum number and the corresponding spin supercurrent can flow without dissipation. Here we explain how spin supercurrents couple spatially remote spin-mixing vertical transport channels, even when easy-plane anisotropy is imperfect, and discuss the possibility that this effect can be used to fabricate new types of electronic devices.

  7. The resistance of 1 nm thick permalloy thin films at room temperature is [8] ∼200Ω/□. The resistance area product of the Co/Cu metal stacks is typically near 10−15Ωm2 [9]. For a permalloy link of widths of ∼5×10−8 m, and a lateral dimension of the metal stacks of ∼10−7 m, the link resistance (∼100Ω) is substantially larger than the stack resistance (∼0.1Ω). Crosstalk has little influence on device performance unless the stack resistance is comparable to the link resistance.
