A magnetic field model of rectangular permanent magnets in a magnetic pendulum array

AIP Advances, 2023
The magnetic pendulum array (MPA) is a novel mechanical antenna for efficient and portable ultra-low-frequency transmission. Its natural frequency is affected by the magnetic field of its rectangular permanent magnets.

The influence of demagnetization on the magnetic after-effect of Co-Cr micro structures [PDF]

, 1993
The influence of the demagnetization field on the magnetic after-effect of Co-Cr media is discussed. The demagnetizing field of as-sputtered Co-Cr was changed into block-shaped micro structures by lithographic processes.

Nondestructive Detection of Magnetic Contaminant in Aluminum Casting Using Thin Film Magnetic Sensor

Sensors, 2021
The thin film magneto-impedance sensor is useful for detecting a magnetic material nondestructively. The sensor made by single layer uniaxial amorphous thin film has a tolerance against surface normal magnetic field because of its demagnetizing force in ...

Nonlinear conjugate gradient methods in micromagnetics

AIP Advances, 2017
Conjugate gradient methods for energy minimization in micromagnetics are compared. The comparison of analytic results with numerical simulation shows that standard conjugate gradient method may fail to produce correct results. A method that restricts the

Dynamics of a ferromagnetic domain wall and the Barkhausen effect [PDF]

, 1997
We derive an equation of motion for the the dynamics of a ferromagnetic domain wall driven by an external magnetic field through a disordered medium and we study the associated depinning transition.

An Approach to Monitoring of Magnetic Parameters of Cores of a Chain of Spheres. Diagnostics of Different Chain’s Length and Core’s Radius

Приборы и методы измерений, 2022
The basic structural elements of the magnetized granular medium (effectively used, in particular, in apparatus of thin magnetic separation) are granule chains (according to channel-by-channel model), in connection with which there is a need to detail the
