Three novel one-dimensional (1D) lanthanide coordination complexes involving the 4-methyl-3-nitrobenzoic acid (HL) ligand, with the general formulae [Gd(L)3(H2O)(CH3OH)] (1), [Gd(L)3(H2O)2]·(4,4'-bpy)·CH3OH (2), [Dy(L)3(H2O)(CH3OH)] (3), have been synthesized by solvothermal reactions. These complexes have been structurally characterized by single-crystal X-ray diffraction, IR, PXRD, TGA, and e...

modeling of 3-legged, 3-phase transformers under DC biasing is a challenging topic due to the need to have an adequate representation of flux paths beyond the active part including the tank. The main contribution of this paper is to present a new dual circuit model which takes the off—core flux path into consideration. An equivalent circuit is developed for this off-core path including equivale...

A special nanopillar comprised of a thick top ferromagnetic layer and a thin bottom ferromagnetic layer is fabricated and the transport properties are measured by applying a dc current and an external field. It is shown experimentally that the dc current flowing through the nanopillar could lead to intermediate states between the antiparallel and the parallel magnetic configurations. The interm...

We introduce a method to improve the detection sensitivity for the magnetization M of superparamagnetic nanoparticles (MNP). The M response of MNP to an applied magnetic field H (M-H characteristics) could be divided into a linear region and a saturation region, which are separated at a transition point H(k). When applying an excitation magnetic field (H(ac)) with a frequency ω0 and an addition...

Magnetization reversal in a many-spin nanomagnet subjected to an rf magnetic field, on top of DC is studied by numerically solving the system coupled (damped) Landau-Lifshitz equations. It demonstrated that spin-misalignment induced surface anisotropy favors switching with field weaker than Stoner-Wohlfarth for optimal intensities and frequencies field.

We present results of AC and DC magnetic moment measurements on a Pb(50 nm)/Cu(10 nm) bilayer film with a triangular antidot lattice of spacing 866 nm and diameter 350 nm. The sharp peaking of matching anomalies in the AC and DC magnetization curves indicates a proximity coupling of the Pb and Cu layers, which is also supported by an asymmetric splitting of matching peaks in AC moment data. Thi...

MOSFET is the most commonly used devices in DC-DC power converters, and its performance is important to the prognosis and health management of power. The paper proposes a degradation analysis model for MOSFET in DC-DC power converters. A method for detecting the degradation of MOSFET is also introduced. Simulations have shown that the method can predict deterioration in the performance of MOSFE...

We investigate transverse charge and spin dc supercurrents in a ferromagnet coupled to superconductor where the has inhomogeneous magnetic structure. These arise from nontrivial structure of magnetization. The manifested supercurrent is essentially different that discussed context anomalous Hall effect, reflecting dissipationless nature supercurrent. Possible candidates verify our prediction ar...
