Vortex Core-Driven Magnetization Dynamics
Science, 2004Time-resolved x-ray imaging shows that the magnetization dynamics of a micron-sized pattern containing a ferromagnetic vortex is determined by its handedness, or chirality. The out-of-plane magnetization in the nanometer-scale vortex core induces a three-dimensional handedness in the planar magnetic structure, leading to a precessional motion of the ...

Pulse Magnetization of Strap Toroidal Magnetic Core
IEEE Transactions on Plasma Science, 2019Diffusion of the pulse magnetic field into the metal of the toroidal magnetic core wound by a transformer steel strap is considered. The 1-D numerical model has been developed, which takes into account the viscous-type dynamic losses of magnetization, as well as the eddy currents.

Abstract A transformer made for impedance matching of detector and preamplifier is considered like a dissipative two-port network. The noise voltage, induced by ferrite core of transformer on the receiver end, is derived from first principles. An inductance of transformer windings is considered to be finite and no additional shunt magnetizing ...

Magnetic dust cores for inductances operating above power frequencies are manufactured from very finely divided magnetisable material, each metal particle being insulated from all its neighbours. The metal powder is of such a fine subdivision that it is commercially known as metal dust.

A number of the more commonly known magnetic core access switches are combined in a single analytical model. In addition to yielding as special cases the known access switches on which it is based, this model produces many apparently new switches. Relationships among the various parameters in this model are developed in such a way that the designer may

In a metal-insulator alternate type multilayer head core usable for magnetic sound recording and reproducing, metallic component layers are connected to each other via one or more metallic interconnecting layers passing locally through insulating component layers in order to provide high effective permeability with minimized eddy current loss.

Core loss in buried magnet permanent magnet synchronous motors
IEEE Transactions on Energy Conversion, 1989The steady-state core-loss characteristics of buried-magnet synchronous motors operating from a sinusoidal constant frequency voltage supply are investigated. Measured and calculated core loss, with constant shaft load, is shown to increase with decreasing terminal voltage due to an increase in armature reaction-induced stator flux-density time ...

Core−Shell-Structured Magnetic Ternary Nanocubes
Journal of the American Chemical Society, 2010We report a novel core-shell-structured ternary nanocube of MnZn ferrite synthesized by controlling the reaction temperature and composition in the absence of conventionally used reducing agents. The highly monodispersed core-shell structure consists of an Fe(3)O(4) core and an MnZn Ferrite shell.

Magnetically responsive liquid core polyelectrolyte nanocapsules
Journal of Microencapsulation, 2014The aim of this work was to develop the method of preparation of magnetically responsive, loaded nanocapsules based on a liquid core encapsulation by polyelectrolyte (PE) multilayer adsorption. Magnetically responsive drug nanodelivery systems were prepared by the sequential adsorption of PEs (layer-by-layer technique) using biocompatible PEs (poly-l ...
