In this paper, we theoretically studied the tunable dynamic microwave properties of a magnetic skyrmion manipulated by strains through micromagnetic simulations. The strains are induced by voltage due to the converse piezoelectric effect and then app

We have developed a spintronic theory for magnetic tunnel junctions consisting of a single-crystal barrier and two half-metallic ferromagnetic electrodes. Radically different from the conventional theories, the barrier is now regarded as an optical d

c-oriented Cu doped e-Fe2–3N films are fabricated on c-Al2O3 by magnetron sputtering. It is found that the crystal constant c decreases with increasing Cu doping amount, which is due to the smaller radius of Cu atoms. The XPS peaks of Fe 2p and Cu

The band structure of Fe-N film is studied by angle resolved photoemission spectroscopy. It is found that the 3d band of Fe-N film disappears due to the hybridization of Fe 3d states and N 2p states. The result can account for the less ferromagnetism

Single phase c-oriented e-Fe2∼3N films are grown on c-Al2O3 substrate by magnetron sputtering. Due to small lattice mismatch between e-Fe2∼3N and Al2O3 substrate (i.e. −0.54% for e-Fe2N and 1.4% for e-Fe3N), the e-Fe2∼3N films present only c-

We investigate the current-driven characteristics and applications of magnetic skyrmion strings by micromagnetic simulations. Under the spin-polarized driving current, the skyrmion string presents different moving trajectories in different layers due

We have developed a tunneling theory to describe the temperature dependence of tunneling magnetoresistance (TMR) of the magnetic tunnel junctions (MTJs) with periodic grating barrier. Through the Patterson function approach, the theory can handle eas

Magnetic and transport properties of iron nitride compounds are closely related to the ratio of Fe:N. In this letter, we report a successful growth of pure single-phase N-rich iron nitride (e-Fe2–3N and γ″-FeN) films on Al2O3. e-Fe2–3N shows a

Plasmonic nanolaser as a new type of ultra-small laser, has gain wide interests due to its breaking diffraction limit of light and fast carrier dynamics characters. Normally, the main problem that need to be solved for plasmonic nanolaser is high los

In this paper, we shall demonstrate firstly that a normal incidence can be totally reflected from a slab made of active metamaterial with purely-imaginary-impedance. Then we shall predict that a localized steady state of electromagnetic wave dependen
