We demonstrated a magnetic tunnel junction (MTJ) consisting of Fe/MgO-Si-MgO/Fe. Si layer was deposited at room temperature and at 700 °C; when deposited at 700 °C, Si diffused into the MgO layer. The MTJ with silicon deposited at 700 °C attained

In this study, we quantitatively discuss several kinds of thermal resistances that rise up to the surface in thermal management of automotive SiC-based on-board inverters with extremely high heat flux of 500 W/cm2. It is proven that a stacking struct

We have investigated an approximated analytic form of the one-dimensional motion of skyrmions accelerated by a gradient of the external magnetic field. We find excellent agreement between the analytical calculations and micromagnetic simulations when

We propose hybrid phase modulation (PM)/frequency modulation (FM) atomic force microscopy (AFM) to increase the imaging speed of AFM in high-Q environments. We derive the relationship between the phase shift, the frequency shift and the tip–sample

We demonstrated for the first time physically unclonable functions (PUFs) based on voltage-controlled magnetic tunnel junctions (VC-MTJs). The proposed PUF completely extracts the intrinsic variation of magnetization switching in the VC-MTJ as a rand
We propose hybrid mode atomic force microscopy (AFM) of phase-modulation (PM) and frequency-modulation (FM) in constant amplitude (CA) mode to increase imaging speed of AFM in high-Q environments. We derive the relation among the phase shift, frequen

Magnetic skyrmions are currently gaining attention owing to their potential to act as information carriers in spintronic devices. However, conventional techniques which rely on modulating the electric current to write or manipulate information using
