Arc plasmas have promising applications in many fields, and exploring their properties is of interest. This research paper presents detailed pressure-based finite volume simulations an argon arc. Simulations the free-burning arc show good agreement with experiment. We observe interesting phenomenon that concentrates intensively a high-frequency alternating longitudinal magnetic field. different...

High density magnetic domain wall gratings are imprinted in ferromagnetic-antiferromagnetic thin films by local ion irradiation by which alternating head-to-tail-to-head-to-tail and head-to-head-to-tail-to-tail spatially overlapping domain wall networks are formed. Unique magnetic domain processes result from the interaction of anchored domain walls. Non-linear magnetization response is introdu...

We analyze the magnetic excitations of a spin-1/2 antiferromagnetic Heisenberg model with alternating nearest neighbor interactions and uniform second neighbor interactions recently proposed to describe the spin-Peierls transition in CuGeO3. We show that there is good agreement between the calculated excitation dispersion relation and the experimental one. We have also shown that this model rep...

Introduction: Physical factors such as electromagnetic fields and chemical agents such as aluminum compounds can act as oxidative stress inducer. In the present study synergistic and toxic effects of aluminum in the presence of an alternating electromagnetic field is investigated. In order to make the protection the extract of Myrtus Communis was used Materials and Met...

Abstract As an advanced downhole instrument in drilling engineering, fluid continuous wave generator (DFCWG) has great application prospects. The large load torque is one of the key problems that hinder development DFCWG. In this paper, based on design theory rotary valve and finite element method, structure designed characteristics analyzed points out strong alternating characteristics. It poi...
