The lack of corrosion resistance limits the application most conventional soft magnetic materials (SMMs) in a corrosive environment, especially seawater. Hence, enhancing SMMs is critically important. However, severe contradiction exists between properties and as main anticorrosion element Cr has strong anti-ferromagnetism that deteriorates magnetism alloys. This study aimed to report novel sin...

The soft chemical method was adopted for the synthesis of cobalt substituted nickel-zinc and zinc-nickel ferrites (Ni0.95-xZn0.05CoxFe2O4 Zn0.95-xNi0.05CoxFe2O4 x= 0.01, 0.02, 0.03, 0.04, 0.05, 0.06. We have recently studied structural, morphological, magnetic properties, initial permeability, dielectric constant samples. They are found with cubic ferromagnetic spinel structure along morphology...

A pair of isostructural bis-selenathiazolyl and bis-diselenazolyl radical conductors display weak (spin-canted) ferromagnetism with Tc values of 18 K and 27 K respectively.

Potassium nanoclusters in aluminosilicate zeolite A shows ferromagnetic properties, although bulk metal of K is nonmagnetic. K clusters are prepared by adsorbing guest K atoms into the supercages (α cages) of dehydrated zeolite A, where supercages with the inside diameter of ∼ 11 Å are arrayed in a simple cubic structure. By the loading of guest K atoms, s-electrons are provided for clusters, a...

I present a stochastic population model that combines cooperative interactions of the type often used in physics with the process of reproduction and death familiar to biology, and I refer to reasons why such interlocking may be of interest to both fields. Physics and biology have developed good frameworks to model the process of stochastic change in systems which experience the action of coope...

Fully understanding the properties of n-type ferromagnetic semiconductors (FMSs), complementary to mainstream p-type ones, is a challenging goal in semiconductor spintronics because ferromagnetism FMSs theoretically non-trivial. Soft-x-ray angle-resolved photoemission spectroscopy (SX-ARPES) powerful approach examine mechanism carrier-induced FMSs. Here our SX-ARPES study on prototypical FMS (I...

We investigate near-Fermi-energy (EF) element-specific electronic and spin states of ferromagnetic van der Waals (vdW) metal Fe5GeTe2. The soft x-ray angle-resolved photoemission spectroscopy (SX-ARPES) measurement provides spectroscopic evidence localized Fe 3d band. also find prominent hybridization between the band delocalized Ge/Te p bands. This picture is strongly supported from direct obs...

We study the existence of minimizers for 2-dimensional ferromagnetism with various assumptions on different terms of the total energy. Our general philosophy for finding the minimizing magnetizations is to reduce this problem to a minimization problem for a new energy over a divergence-free field. Such a general philosophy works for all dimensions. However, in the twodimensional case, since the...

Symmetry breaking ground states occur in quantum Hall effect (QHE) systems when two or more Landau levels become degenerate near the Fermi level. Isotropic, easy-axis or easy plane quantum Hall ferromagnets (QHF) can form depending on the pseudospins of the involved Landau levels consisting of real spin, orbit radius quantum number, subband index or growth direction. Theories based on Hartree-F...
