Angular Dependence of Magnetization Behavior in Ni81Fe19 Nanowires by Micromagnetic Simulations
Nickel (Ni)-iron (Fe) alloy in the form of Ni81Fe19 (permalloy) is a widely used material in technological soft magnetic applications. Understanding the magnetization behavior in detail in such materials is substantial from both a scientific point of ...

A novel nanomedicine is synthesized based on Fe3O4 vortex nanorods loaded with doxorubicin (DOX) and EZH2 siRNAs and coated with a macrophage membrane. It shows a preferential tumor enrichment profile, thus leading to highly efficient drug delivery at the tumor site.

Current‐driven split and integration of the elliptically distorted skyrmions are realized. At a current density of 3.8 × 1010 A m−2, the elliptical skyrmions split into two circular skyrmions. More importantly, such a transition is reversible, which is beneficial for memory applications. The results establish a viable approach to manipulating skyrmions,

Spontaneous Topological States and Their Mutual Transformations in a Rare‐Earth Ferrimagnet
Spontaneous magnetic biskyrmions and successive topological transformation into traditional magnetic bubbles via (bi‐)target bubbles are directly observed in a tetragonal ferrimagnetic crystal DyFe11Ti by changing the temperature using in situ Lorentz transmission electron microscopy.

Using OOMMF to Study the Effect of Microstructure on Magnetic Hysteresis Loops
This paper presents a study of the effect of magnetic material parameters and microstructure on macroscopic magnetic properties with the open-source soft-ware for micromagnetic calculations OOMMF. Micromagnetic calculations are carried out using direct energy minimization.

Active Ferromagnetic Metasurface with Topologically Protected Spin Texture for Spectral Filters
Metasurfaces provide control over electromagnetic waves, which goes beyond natural materials. They consist of precisely engineered hybrid materials. By the combination of ferromagnetic nanodisks hosting topologically protected vortex states with a ferrimagnetic thin film, a metasurface is created which shows magnetically switchable microwave filtering ...

Spin Wave Electromagnetic Nano‐Antenna Enabled by Tripartite Phonon‐Magnon‐Photon Coupling
Tripartite phonon‐magnon‐photon coupling in a 2D array of two‐phase multiferroic nanomagnets implements a novel ultra‐sub‐wavelength electromagnetic antenna whose gain and radiation efficiency exceed the theoretical limits for traditional antennas of the same dimensions by many orders of magnitude at some (≈GHz) frequencies.
