摘要：
Quantum corrections to the conductivity of a mesoscopic ring in a nonstationary magnetic field with the flux Phi(t) = Vt are investigated. The time dependence of the quantum corrections shows periodic cusps with a period corresponding to the magnetic flux quantum Phi(0) = hc/2e. If the characteristic time of the magnetic flux variation tau(0) = Phi(0)/V is much smaller than the phase relaxation time tau(phi), the cusps become asymmetrical.
