Creating substantial temperature gradient along bulk samples, gradual superconductingnormal or normal-superconducting transition has been revealed by the measurement of a.c. susceptibility. Different domains transform into superconducting or normal state depending on the local properties of the grains and islands which cause an inhomogeneous transition. Electron optical investigation of the structure of samples proves it to be a fundamental behaviour of the material. This represents an indispensable feature for designing superconducting fault current limiters or high power electric and magnetic equipments.
