We demonstrate via micromagnetic simulations that a magnetic domain, which has two straight domain walls (DWs) and is formed in a perpendicularly magnetized ferromagnetic metal (FM), moves through a perpendicularly magnetized ferromagnetic insulator

Magnetic-skyrmion-based racetrack memory is a high-density memory for storing information driven by low-power, wherein the arrangement of skyrmions is stored in the form of binary digit combinations. This arrangement is altered based on the skyrmion

We propose a racetrack memory (RM) with a continuous loop structure built from a nanowire comprising a ferromagnetic insulator (FI) and a ferromagnetic metal (FM) junction. We demonstrate via micromagnetic simulations that a magnetic domain formed in

A magnetic skyrmion is stabilized via the Dzyaloshinskii–Moriya interaction in a perpendicularly magnetized thin nanowire. When the skyrmion is driven by a spin-transfer torque due to spin currents flowing through the wire, the skyrmion approaches

The tunnel magnetoresistance (TMR) of ferromagnetic junctions including twisted magnetization near the insulator barrier has been theoretically studied using linear response theory and a single orbital tight-binding model. The region of the twisted m

Numerical results of electrical conductance and magnetoresistance of ferromagnetic tunnel junctions and semiconductor/semimetal junctions are presented, putting an emphasis on effects of disorder on the conductance. It is shown that the disorder stro

Current-induced magnetic domain wall (DW) motion in ferromagnetic ribbons is utilized in spintronic devices. The direction of the motion changes in response to the sign of the spin-polarizability of the current through the ribbon. The DW motion is ex
