Review of Double Stator Flux switching machines with various arrangements of excitation sources

open access: yesAlexandria Engineering Journal, 2021
Nowadays flux switching machines (FSMs) offer important role in various high torque applications. In these machines, the flux sources such as field excitation coil (FEC), armature winding and permanent magnet (PM) are located in the stator while leaving ...

Meissner state in finite superconducting cylinders with uniform applied magnetic field

open access: yes, 1999
We study the magnetic response of superconductors in the presence of low values of a uniform applied magnetic field. We report measurements of DC magnetization and AC magnetic susceptibility performed on niobium cylinders of different length-to-radius ...

Irreversible demagnetization mechanism of permanent magnets during electromagnetic buffering

open access: yesDefence Technology, 2021
The permanent magnets will be irreversibly demagnetized under high temperature and high velocity during the electromagnetic buffering. In this study, the magnetic field induced by eddy currents and the self-demagnetizing field of permanent magnet are ...

Computing the demagnetizing tensor for finite difference micromagnetic simulations via numerical integration

open access: yes, 2015
In the finite difference method which is commonly used in computational micromagnetics, the demagnetizing field is usually computed as a convolution of the magnetization vector field with the demagnetizing tensor that describes the magnetostatic field of

Magnetic characterization of perpendicular recording media [PDF]

open access: yes, 2002
In this paper, we describe techniques for the magnetic characterization of perpendicular recording media. Such measurements made using traditional techniques, such as the vibrating sample magnetometry (VSM) and alternating gradient force magnetometer ...

The demagnetization field of multidomain grains.

open access: yesJournal of geomagnetism and geoelectricity, 1977
The demagnetization ‘constant’, N, enters into all theoretical considerations of multidomain remanence. Although most workers believe N to be related simply to the shape of the grain, no theoretical study of N has previously been completed. It is shown in this paper thatN monotonically increases with increase in remanence in multidomain grains ...

Nonlinear excitations in CsNiF3 in magnetic fields perpendicular to the easy plane

open access: yes, 2003
Experimental and numerical studies of the magnetic field dependence of the specific heat and magnetization of single crystals of CsNiF3 have been performed at 2.4 K, 2.9 K, and 4.2 K in magnetic fields up to 9 T oriented perpendicular to the easy plane ...

The effect of the initial layer on the reversal mechanism in CoCr films [PDF]

open access: yes, 1988
The dependence of OR, H/sub c/, and hysteresis loss is measured as functions of the angle with the applied field (H/sub a/) as a parameter. It is reported that with increasing H/sub c/ perpendicular to /H/sub k/ values the orientation direction of the ...
