Effect of the temperature on the high-frequency electric impedance of amorphous soft magnetic cobalt-based wires is investigated. A high sensitivity of their impedance to the transition of the ferromagnetic state into the paramagnetic state is demonstrated. The temperature dependences of the impedance measured at different alternating current frequencies allow a distribution of the magnetic phases in the wire volume to be elucidated.
