A temperature sensor has a body whose thermal expansion is evaluated in the event of a change in temperature, there being deposited on the body a layer which has a layer structure containing less than 8% by weight of phosphorus, preferably containing up to 3% by weight of phosphorus, up to 2% by weight of an element of main group IV or main group V, in particular antimony, and up to 5% by weight of a transition metal element, in particular cobalt. The percentages by weight resulting from the sum being increased up to 100% with nickel. The layer modifies the magnetic flux in a coil arrangement comprising at least one coil. This change in the magnetic flux in the coil arrangement is evaluated and the change in the magnetic flux being detected as a change in the inductance. The change in length of the body and the change in temperature are deduced therefrom.
