Investigating Size- and Temperature-Dependent Coercivity and Saturation Magnetization in PEG Coated Fe3O4 Nanoparticles

Magnetochemistry, 2017
Polyethylene glycol (PEG) coated magnetic Fe3O4 nanoparticles with diameters of 12 nm, 15 nm, and 16 nm were synthesized by the usual co-precipitation method.

Effects of Magnetizing Yoke Design on the Magnetic Properties of Nd₂Fe₁₄B Permanent Magnet for Electric Vehicle Motor Applications

Applied Sciences, 2022
When the uniformity of the magnetization yoke is low, a mismatch occurs between the physical rotation center and the center due to the magnetic force after magnetization.

Quasi-Spin Correlations in a Frustrated Quantum Spin Ladder [PDF]

, 2015
The quasi-spin correlations in a frustrated quantum spin ladder with one-half magnetization are theoretically studied by using the density-matrix renormalization-group method and the quasi-spin transformation.

Magnetization dynamics and reversal of two-dimensional magnets [PDF]

arXiv, 2022
Micromagnetics simulation based on the classical Landau-Lifshitz-Gilbert (LLG) equation has long been a powerful method for modeling magnetization dynamics and reversal of three-dimensional (3D) magnets. For two-dimensional (2D) magnets, the magnetization reversal always accompanies the collapse of the magnetization even at low temperatures due to ...

Magnetization Process of Kagome-Lattice Heisenberg Antiferromagnet

, 2010
The magnetization process of the isotropic Heisenberg antiferromagnet on the kagome lattice is studied. Data obtained from the numerical-diagonalization method are reexamined from the viewpoint of the derivative of the magnetization with respect to the ...

Engineered Magnetization Dynamics of Magnonic Nanograting Filters

Magnetochemistry, 2021
Magnonic crystals and gratings could enable tunable spin-wave filters, logic, and frequency multiplier devices. Using micromagnetic models, we investigate the effect of nanowire damping, excitation frequency and geometry on the spin wave modes, spatial ...

Impulse Magnetized Magnetic Screws [PDF]

IEEE Transactions on Magnetics, 2019
This paper is an investigation in the performance of two types of magnetic screws (MSs). The first is the magnet to magnet and consists of permanent magnet (PM) nut and PM screw and the second is a magnet to reluctance and consists of PM nut and a double-start reluctance screw.

Magnetization switching by microwaves initially rotating in opposite direction to precession

, 2015
A common understanding of magnetization switching in microwave-assisted magnetization reversal is that the rotation direction of the microwaves should be the same with the precession direction of the magnetization.
