Abstract
The magnetic resonance line of conduction electrons in solids may exhi bit bistable hysteresis if several conditions are fulfilled. Its mecha nism is presented and the manifestation of bistability in the ESR of c onduction electrons in single crystal and polycrystalline samples is d iscussed. The characteristics of the dynamics of the bistability show that bistable resonance can be assimilated to one-dimensional overdamp ed motion of the spin system in the nuclear field space, driven by a b istable potential. it is shown for the first time that noise acting on this bistable resonance can create order, by the phenomenon of stocha stic resonance.
