Macroscopic Random Telegraph Noise

It is proposed that macroscopic telegraph noise in superconductors is due to dynamic coexistence of ordered and disordered vortex phases (DP and OP) created by edge contamination mechanism. A novel, robust, with bias insensitive rates, macroscopic telegraph noise in low Ca-doped manganites is ascribed to the dynamic current redistribution assisted by a positive resistance feedback associated with Meyer–Neldel compensation rule.
