We have investigated a coupled motion of two parallel vortex cores in ferromagnetic/nonmagnetic/ferromagnetic trilayer cylinders by means of micromagnetic simulation. Dynamic motion of two vortices with parallel and antiparallel relative chiralities of curling spins around the vortex cores have been examined after excitation by 1 ns pulsed external field, revealing a nontrivial coupled vortices motion.

    We report first principles calculations of transport properties of the all-oxide La2/3Sr1/3MnO3/MgO/SrRuO3 magnetic tunnel junctions. A sizeable rectifying behavior which can be enhanced by increasing the MgO barrier thickness is predicted theoretically. For the device with 13 layers of MgO...

    Creating, imaging, and transforming the topological charge in a superconductor, a superfluid, a system of cold atoms, or a soft ferromagnet is a difficult-if not impossible-task because of the shortness of the length scales and lack of control. The length scale and softness of defects in liquid...
