Patent ID: 8779765

Claim:
A method for forming spin waves in a graphene film, comprising: selecting a working area of the graphene film having a linear dimension of 2,000 nm, dividing the working area into sections having a dimension of 50-100 nm, applying a pulsed alternating magnetic field from a pumping structure to the working area having a frequency of 3 terahertz that corresponds to the transition from the ground energy level corresponding to the non-excited state of spin density to the fourth working energy level of the excited state of spin density in the graphene film, wherein energy pumping of spin density is caused, wherein a spatially localized external magnetic field is formed at the edges of the working area, wherein spinons are resonantly reflected having a working frequency of 0.5-1 terahertz corresponding to the transition from the third working energy level to the second working energy level of the excited state of spin density, and wherein the spinons, when they pass through the working area, cause induced coherent emission of working frequency spin waves.
