Abstract: The influence of temperature on the magnetic properties and magnetoimpedance of Co$_{64}$Fe$_3$Cr$_3$Si$_{15}$B$_{15}$ and Co$_{67}$Fe$_3$Cr$_3$Si$_{15}$B$_{12}$ amorphous ribbons having different Curie points are studied. The impedance and its component are found to change greatly when the ribbons pass into the paramagnetic state. This finding can be used to determine the Curie point of ferromagnets and design high-sensitivity thermal transducers.
