This disclosure describes various examples of spintronic temperature sensors. The example temperature sensors may be discrete or used to adaptively control operation of a component such as an integrated circuit (IC). In one example, an electronic device comprises a spintronic component configured such that the conductance of the spintronic component is based on sensed temperature. In one example, circuitry coupled to the spintronic component is configured to generate an electrical signal indicative of the sensed temperature based on the conductance of the spintronic component.
