The investigation into the temperature dependence of magnetoimpedance (MI) response in soft magnetic materials is important for controlling the thermal stability of MI-based sensor devices as well as for developing the miniature temperature- sensing elements. Two different mechanisms of MI temperature effects, namely, the internal stress relaxation upon heating and approaching the Curie temperature T_c are considered. In both cases, sensitive change in impedance for moderate temperature range (<100 C) can be observed.
