Magneto-rheological elastomers (MREs), a class of polymer-based composites with dispersed magnetic filler particles, are known for their tunable stiffness. The magnetic-field-induced stiffening effect, namely the magneto-rheological (MR) effect, is often attributed to the magnetic dipolar interaction. The direct attraction between two magnetic dipoles could increase the shear modulus of the mat...

Manipulation of the domain wall propagation in magnetic wires is a key practical task for a number of devices including racetrack memory and magnetic logic. Recently, curvilinear effects emerged as an efficient mean to impact substantially the statics and dynamics of magnetic textures. Here, we demonstrate that the curvilinear form of the exchange interaction of a magnetic helix results in an e...

Molecular dynamics model calculations for the thermal decomposition of N2O with external magnetic field were performed. The effect of external magnetic field was modeled by parameterization of the interaction term between the singlet and triplet potential surfaces. It was suggested that the increase of the rate constant by external magnetic field could be explained by means of the increase of i...

We consider tensor-bispinor equation, which describes doublets of particles with spin 32 , nonzero masses and anomalous interaction with electromagnetic field. Using this equation we find the energy levels of the particle with spin 32 in constant magnetic field, crossed electric and magnetic fields. We show that it is possible to introduce anomalous interaction in such way that energy levels ar...

General properties of the chiral scattering of polarized neutrons are considered for two possible axial vector interactions: Zeeman energy and non-alternating DzyaloshinskiiMoriya interaction. Behavior in magnetic field of helical magnetic structures is discussed for MnSi and magneto-electric materials. The dynamical chiral fluctuations in magnetic field are considered briefly. The chiral fluct...

The phenomenon of the resistance minimum in dilute magnetic alloys is explained in terms of the s-d interaction which takes account of scattering of the conduction electron off the magnetic impurities in metals. Some of the intermetallic compounds which involve rare earth elements or uranium show a very large electronic specific heat and remain non-magnetic even though they show a Curie-like su...

We present an approach to control the magnetic structure of adatoms adsorbed on a substrate having a high magnetic susceptibility. Using finite Ni-Pt and Fe-Pt nanowires and nanostructures on Pt(111) surfaces, our ab initio results show that it is possible to tune the exchange interaction and magnetic configuration of magnetic adatoms (Fe or Ni) by introducing different numbers of Pt atoms to l...

A new class of phenomena discussed in this review is based on interaction between spatially separated, but closely located ferromagnets and superconductors. They are called Ferromagnet-Superconductor Hybrids (FSH). These systems include coupled smooth and textured Ferromagnetic and Superconducting films, magnetic dots, wires etc. The interaction may be provided by the magnetic flux from magneti...

Introduction: Recently, some studies have focused on dendrimer nanopolymers as an MRI contrast agent or a vehicle for gene and drug delivery. Considering the suitable properties of these materials, they are appropriate candidates for coating iron oxide nanoparticles which are applied to magnetic hyperthermia. To the best of our knowledge, the novelty of this study is the inves...

Plants for optimal growth requires absorb water and nutrients absorption from the soil. Magnetic Water downward movement of minerals and makes it easy for plants to absorb nutrients and water. This study was designed to investigate the effect of magnetic salt water on some quantity and quality characteristics of artichoke leaves. The experiment was factorial based on completely randomized desig...
