FIG. 1.

(Color online) Solutions to the evolution equations: (a) x = x(t); (b) y = y(t); (c) s = s(t); (d) h = h(t) for the parameters ω 0 = ω = 10, ωD  = ω 1 = ω 2 = 1, γ = 1, γ 1 = 10−3. The parameters are measured in units of γ 0 and time, in units of 1/γ 0. To emphasize the role of the resonator feedback field, the solutions in the presence of the resonator (solid lines) are compared with those for the case of no resonator (dashed lines).

(Color online) Role of the resonator attenuation. Magnetization as a function of time for the parameters ω 0 = ω = 10, ωD  = ω 1 = ω 2 = 1, and varying resonator attenuation: (a) γ = 0.1; (b) γ = 1 (solid line), and γ = 10 (dashed line).

(Color online) Role of the Zeeman frequency. Magnetization as a function of time for the parameters ωD  = ω 1 = ω 2 = 1, γ = 1, and varying Zeeman frequency: (a) ω 0 = ω = 1 (solid line) and ω 0 = ω = 10 (dashed line); (b) ω 0 = ω = 100.

(Color online) Role of the triggering field. Magnetization as a function of time for the parameters ω 0 = ω = 10, ωD  = ω 2 = 1, and varying triggering field: (a) ω 1 = 0.001 (solid line) and ω 1 = 1 (dashed line); (b) ω 1 = 10.

(Color online) Role of the anisotropy. Magnetization as a function of time for the parameters ω 0 = ω = 10, ω 1 = 1; γ = 1, and varying anisotropy frequencies ωD  = ω 2 = 1 (dashed-dotted line); ω D = ω 2 = 10 (solid line); ω D = ω 2 = 15 (dashed line).

(Color online) Role of the resonance. Magnetization as a function of time for the parameters ω 0 = 10, ω D = ω 1 = ω 2 = 1, γ = 1, and varying detuning from the resonance, with ω = 1 (solid line); ω = 10 (dashed-dotted line); ω = 20 (dashed line).

FIG. 7.

(Color online) Magnetization reversal in the system of nanoclusters with dipolar interactions. The system parameters are γ 1 = 10−3, Δ = 0, A = 0.1, ω 1 = 0. Time is measured in units of T 2 1/γ 2 = 10−10 s, and the frequencies, in units of γ 2. Other parameters are: γ = 10, ω 0 = ω = 1000, g = 100 (solid line); γ = 1, ω 0 = ω = 100, g = 100 (dashed-dotted line); γ = 10, ω 0 = ω = 100, g = 10 (dashed line). The shown functions of time are (a) coherence intensity w(t); (b) reduced magnetization s(t).
