Multi‐Level Switching of Spin‐Torque Ferromagnetic Resonance in 2D Magnetite

Advanced Science, Volume 11, Issue 26, July 10, 2024.
The synthesis of environmentally stable and high Curie temperature 2D Fe3O4 nanosheets are reported that exhibit multi‐level resistance under the stimulation of a microwave field at room temperature. Such behavior is ascribed to the emergence of bAPBs and sAPBs in the Fe3O4 structure and morphological evolution of spin texture.

A Comprehensive Survey on Particle Swarm Optimization Algorithm and Its Applications

Mathematical Problems in Engineering, Volume 2015, Issue 1, 2015., 2015
Particle swarm optimization (PSO) is a heuristic global optimization method, proposed originally by Kennedy and Eberhart in 1995. It is now one of the most commonly used optimization techniques. This survey presented a comprehensive investigation of PSO.

Field‐Free Spin‐Orbit Torque Driven Perpendicular Magnetization Switching of Ferrimagnetic Layer Based on Noncollinear Antiferromagnetic Spin Source

Advanced Electronic Materials, Volume 10, Issue 4, April 2024.
The authors demonstrate deterministic perpendicular magnetization switching in Mn3Sn/CoTb bilayers by employing a textured Mn3Sn film as the spin source. This study emphasizes the significant contribution of the out‐of‐plane polarized spin current (σz) generated from Mn3Sn to the spin‐orbit torque (SOT) effect.

Miniaturized High‐Isolation Dual‐Frequency Orthogonally Polarized Patch Antenna Using Compact Electromagnetic Bandgap Filters

International Journal of Antennas and Propagation, Volume 2014, Issue 1, 2014., 2014
A miniaturized dual‐frequency dual‐polarization microstrip patch antenna with high isolation between receiving and transmitting ports (operating at 2.1 GHz for receiving and at 2.5 GHz for transmitting) is presented in this paper. The proposed antenna consists of a modified rectangular radiating patch, two 50 Ω microstrip feed lines, and two EBG ...
