Efficiency of spin-injection terahertz oscillator
Yu. V. Gulyaev, S. G. Chigarev, I. V. Malikov +3
Energy efficiency in terahertz range is evaluated experimentally of a spin-injection oscillator based on a ferromagnetic rod-film structure with point contact between the component…
Spin-injection terahertz radiation in magnetic junctions
S. G. Chigarev, E. M. Epshtein, Yu. V. Gulyaev +5
Electromagnetic radiation of 1 - 10 THz range has been found at room temperature in a structure with a point contact between a ferromagnetic rod and a thin ferromagnetic film under…
Tunnel magnetoresistance of Fe3O4/MgO/Fe nanostructures
S. G. Chigarev, E. M. Epshtein, I. V. Malikov +2
A magnetic tunnel junction Fe3O4/MgO/Fe with (001) layer orientation is considered. The junction magnetic energy is analyzed as a function of the angle between the layer magnetizat…
Spintronics of metal ferromagnetic structures: New approaches in the theory and experiments
S. G. Chigarev, E. M. Epshtein, Yu. V. Gulyaev +1
Two channels of the sd exchange interaction are considered in magnetic junctions. The first channel describes the interaction of transversal spins with the lattice magnetization. T…
Tunnel magnetoresistance of magnetic junctions with cubic symmetry of the layers
S. G. Chigarev, E. M. Epshtein, P. E. Zilberman
A tunnel magnetic junction is considered with magnetic hard and magnetic soft layers of cubic symmetry. The magnetic switching is analyzed of the layers by a magnetic field perpend…
