Robust two-level telegraph conductivity noise in phase separated ferromagnetic insulating manganite La0.86Ca0.14MnO3 has been observed in exceptionally wide temperature range 130 K – 185 K in the low-resistivity metastable state of the system. The switching rate of the telegraphic noise was found not to depend on applied magnetic field and bias current. In contrast, the amplitude of the telegraphic...
