Brillouin spectroscopy and micromagnetic simulations are used to study the propagation of magnetostatic spin waves across adjacent nonidentical magnonic crystals. The characteristics spin-wave modes in such a structure depend on geometry slabs, efficient coupling at magnonic-band-gap frequency can be achieved. This combination spatial filtering features leads realization frequency-selective drop filter, which is expected extend functionality demultiplexing applications.
A method for electronic-structure calculations of noncollinear magnetic structures has been developed based on the linear-muffin-tin-orbitals approach. Calculations total energies and moments various spiral-spin-density-wave states fcc iron have carried out. The results obtained show that ground state is state. With increase number valence electrons (as in Co) ferromagnetic ordering stabilizes essentially, whereas decrease Mn) antiferromagnetic spin moments.
We report experimental investigation of spin-wave transport along combined magnonic structures which are comprised the 90°-magnonic bend and adjacent nonidentical magnetic stripes. The latter has form a coupler. Using space-resolved Brillouin light-scattering spectroscopy micromagnetic simulations, we study propagation, transformation, coupling spin waves in structure. show that characteristics such defined strongly by intermodal dipolar coupling. developed structure can operate as...
We report on the spin-wave propagation along a magnonic waveguide with local area of decreased magnetization, which is induced by heating produced focused laser spot. A phase-sensitive Brillouin light scattering technique used to image how spin wave propagates heat landscape. Frequency-selective signal demonstrated. Micromagnetic simulations reveal intermodal interference variation in region after heated area. The proposed way reconfigure magnetization landscape can be devices...
Understanding the stability of magnetic textures in multilayer patterned dots would constitute a significant step toward skyrmion-based applications. Here, we report observation skyrmions nanodots composed multilayers. We examine stabilization various states such as single-domain states, skyrmion horseshoe-like domain structures, and worm-like structures submicrometer (diameters 150–525 nm). Dots are fabricated from Pt/Co/Au that exhibit interfacial Dzyaloshinskii–Moriya interaction...
Impurity states in environments of relaxed crystal lattices around substitutional silicon and carbon impurities at both cation anion sites zinc-blende boron nitride (c-BN) have been investigated by the tight binding-linear combination muffin tin orbitals-atomic sphere approximation (TB-LMTO-ASA) method. The pressure dependence impurity (Si)- (C)-doped c-BN is also range 0%–9% lattice compression. Shifts bands, localization charge distributions under are analyzed.
Abstract The values of nuclear quadrupole coupling constants, asymmetry parameters, the electric field gradients, as well components chemical shift tensor are essential interest when charge and spin distributions in a crystal studied. In simplest way parameters mentioned above can be obtained from NMR data for powders if sufficiently correct methods spectra analysis used.

Abstract Electron paramagnetic resonance is the most effective method of studying electron exchange in biradicals. Experimental EPR spectra for solutions some hydrazyl biradicals are available literature (see Refs. [I,2]), however, interpretation not given.
Abstract Using Brillouin light spectroscopy and micromagnetic simulation methods, we show how the intermodal coupling between two magnonic crystals (MCs) affects signals spatial selection with frequency separation during spin-wave transport. We have experimentally demonstrated control of spin waves (SWs) propagating in non-identical magnonic-crystal microwaveguides near band gap frequency. that propagation direction within MCs different width can be controlled by lateral SWs. Our findings...
We demonstrated numerically the skyrmion formation in ultrathin nanodisks using a magnetic force microscopy tip. found that local field generated by tip significantly affects magnetization state of and leads to skyrmions. Experimentally, we confirmed influence on states disks. Micromagnetic simulations explain evolution during scanning confirm possibility formation. The horseshoe domain is key transition from random labyrinth into state. showed skyrmions probe reliable repetitive procedure....
