Helical domain walls in constricted cylindrical NiFe nanowires
Reducing the magnetic shape anisotropy of a cylindrical NiFe nanowire allows the formation of two vortices with opposite chirality at the two ends. At relatively low aspect ratio these two vorticesExpand

Gateable Skyrmion Transport via Field-induced Potential Barrier Modulation
We report on the influence of pinning potentials on current-driven skyrmion dynamics and demonstrate that skyrmions can be gated via either magnetic or electric fields. When encountering pinningExpand

Highly Efficient Domain Walls Injection in Perpendicular Magnetic Anisotropy Nanowire
Electrical injection of magnetic domain walls in perpendicular magnetic anisotropy nanowire is crucial for data bit writing in domain wall-based magnetic memory and logic devices. Conventionally, theExpand

Spin orbit torques induced magnetization reversal through asymmetric domain wall propagation in Ta/CoFeB/MgO structures
The magnetization reversal induced by spin orbit torques in the presence of Dzyaloshinskii-Moriya interaction (DMI) in perpendicularly magnetized Ta/CoFeB/MgO structures were investigated by using aExpand

Magnetic domain confinement by anisotropy modulation.
The spin configuration in a magnet is in general a "natural" consequence of both the intrinsic properties of the material and the sample dimensions. We demonstrate that this limitation can beExpand

Current-induced three-dimensional domain wall propagation in cylindrical NiFe nanowires
We report on the magnetization configurations in single NiFe cylindrical nanowires grown by template-assisted electrodeposition. Angular anisotropic magnetoresistance measurements reveal that aExpand

Interplay of cell death signaling pathways mediated by alternating magnetic field gradient
The ability to control or manipulate the pathways leading to cell death plays a pivotal role in cancer treatment. We demonstrate magneto-actuation of magnetic nanoparticles (MNPs) to induce differentExpand
