Effect of Magnetized Freezing Extender on Membrane Damages, Motility, and Fertility of Boar Sperm Following Cryopreservation

open access: yesAnimals, 2023
Magnetized water is defined as the amount of water that has passed through a magnet. The magnetic field weakens the hydrogen bonds between the water molecules, leading to the magnetized liquid acquiring special characteristics such as easy supercooling ...

MAGNETIZATION OF AMORPHOUS MAGNETS

open access: yesLe Journal de Physique Colloques, 1979
The temperature dependence of the distribution of the magnetic moment in an amorphous magnet, where the exchange interactions and the magnitude of the magnetic moment at O K are random variables, has been investigated. In particular, we considered the two-limiting cases, the one with the fixed spin and the other with the fixed interaction.

Mechanochemical synthesis and magnetic properties of maghemite

open access: yesVojnotehnički Glasnik, 2011
This work presents the results of an investigation on maghemite (γ -Fe2O3) nanoparticles magnetic properties, which show superparamagnetic behavior i.e. superparamagnetism. Nanoscale maghemite samples were obtained by the mechanochemical method.

Magnetoelectric Coupling Effects in Tb-Doped BiFeO3 Nanoparticles

open access: yesMagnetochemistry, 2023
The magnetic, electric, and optical properties in Tb-doped BiFeO3 nanoparticles as functions of size and doping concentrations were investigated using a microscopic model, taking into account both linear and quadratic magnetoelectric (ME) coupling.

Online Magnetization Trajectory Prediction and Current Control for a Variable-Flux Permanent Magnet Machine

open access: yesIEEE Access, 2020
Online magnetization current control is a critical concern of the variable-flux permanent magnet machine control. Increasing the magnetization speed benefits the machine system, which reduces manipulation losses and mechanical impact.

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

open access: yes, 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.

Preparation of Magnetic Nanoparticles via a Chemically Induced Transition: Role of Treating Solution’s Temperature

open access: yesNanomaterials, 2017
Using FeOOH/Mg(OH)2 as precursor and FeCl2 as the treating solution, we prepared γ-Fe2O3 based nanoparticles. The FeCl2 treating solution catalyzes the chemical reactions, dismutation and oxygenation, leading to the formation of products FeCl3 and Fe2O3,

Transport in the XX chain at zero temperature: Emergence of flat magnetization profiles [PDF]

open access: yes, 1998
We study the connection between magnetization transport and magnetization profiles in zero-temperature XX chains. The time evolution of the transverse magnetization, m(x,t), is calculated using an inhomogeneous initial state that is the ground state at ...
