Spin velocity equation
WebThe propagation of spin waves is described by the Landau-Lifshitz equation of motion: where γ is the gyromagnetic ratio and λ is the damping constant. The cross-products in this forbidding-looking equation show that the propagation of spin waves is governed by the torques generated by internal and external fields.

WebApr 14, 2024 · The group velocity of light is defined by v g = c/n g, where n g is the group index. Slotted slow light waveguides have already been proven to exhibit small group velocities down to v g = 0.02c [13], [14]. The group velocity v g of light with frequency ω in an optical waveguide is given as: (2) v g = d z d t = Δ ω Δ k = d ω d k, where k is ...
Webz, the angular velocity about the spin axis, is constant. Inserting this result into the two remaining equations gives I 0ω˙ x = ((I 0 − I)ω z)ω y (10) I 0ω˙ y = −((I 0 − I)ω z)ω x. (11) Since ω z is constant, this gives two linear equations for the unknown ω x and ω y. Assuming a solution of the form ω x = A xeiΩt and ω y = A
