Abstract
We study an interesting state with a self-generated magnetic flux in a long Josephson junction. The critical current density jc is assumed to alternate randomly along the tunnel contact on a length scale much less than the local Josephson penetration depth. The phase difference is then a sum of an alternating term and a smooth term which self-consistently contribute to the formation of a stationary state with self-generated flux. Two types of Josephson vortices are found in this state, one with magnetic flux Φ1<Φ0/2 and another one with magnetic flux Φ2=Φ0−Φ1>Φ0/2.
