A concern with the isolation transformer in a dual active bridge (DAB) dc–dc converter is dc bias magnetization. This article proposes fluxgate-based current sensor to measure component mixed large, high-frequency ac current. Compared commercial Hall effect sensor, proposed significantly reduces measurement error. presents working principle and design considerations. prototype demonstrated for ...

The low-temperature dynamics of a magnetic nanoparticle system sg-Fe2O3—alginate nanocomposite with average particle size around 4 nmd have been studied by superconducting quantum interference device measurements. Using different temperature and field protocols, memory phenomena in the dc magnetization and magnetic relaxation have been observed at temperatures below its blocking temperature TB=...

The domain wall movement and magnetization rotations processes are separated experimentally in quasi-static magnetization process of a Finemet type ultrasoft magnetic material. The reversible domain rotations contribution is obtained from the integration of the reversible permeability, μDR, as a function of biasing DC field, measured with very small alternative field amplitude, less than 0.05Hc...

We study charge transport through a metallic dot coupled to a superconducting and a ferromagnetic lead with a precessing magnetization due to ferromagnetic resonance. Using the quasiclassical theory, we find that the magnetization precession induces a dc current in the subgap regime even in the absence of a bias voltage. This effect is due to the rectification of the ac spin currents at the int...

distribution of exchange interactions is due to the substitution between zinc and cadmium on tetrahedral sites. The samples in powder form were performed by the classical ceramic method. For the crystal growth, different methods were used depending on Zn and Cd concentrations. The composition was determined by X-ray measurements of the lattice constant. The direct current susceptibility measure...

A computer calculation technique of Lorentz microscopy image was developed and was applied to the analysis of the Lorentz microscopy image and magnetic domain structure of a weakly ordered FePt:C thin film for recording media. The magnetic domain structure was, at the as-deposited random state, a vortex network structure and evolved into the islandlike elongated reverse domain structure at the ...

We derive a phenomenological theory of current-induced staggered magnetization dynamics in antiferromagnets. The theory captures the reactive and dissipative current-induced torques and the conventional effects of magnetic fields and damping. A Walker ansatz describes the dc current-induced domain-wall motion when there is no dissipation. If magnetic damping and dissipative torques are included...

The low temperature dynamics of a magnetic nanoparticle system Ni3[Cr(CN)6]2 with an average nanoparticles size of 4 nm was studied. Using different temperature and field protocols memory phenomena were studied by the DC magnetization and magnetic relaxation measurements of the system at temperatures below Tm = 19 K. Aging experiments show an absence of any waiting time dependence in the magnet...

We report observation of coherent quantum oscilations in spin-10 Fe8 molecular clusters. The powder of magnetically oriented Fe8 crystallites was placed inside a resonator, in a dc magnetic field perpendicular to the magnetization axis. The field dependence of the ac-susceptibility was measured up to 5 T, at 680 MHz, down to 25 mK. Two peaks in the imaginary part of the susceptibility have been...

Magnetic resonance effects have been long studied and used for various spectroscopic methods1–3. Timedependent external fields being an integral part of the physical setups, become also very interesting in their action when entering the field of spintronics and processing of quantum information. While the linear response of a system (probe) to external fields may be typically understood in a ra...
