18. An aerosol-generating system, comprising:
an aerosol-generating article; and
an aerosol-generating device for the aerosol-generating article,
wherein the aerosol-generating article comprises:
an aerosol-forming substrate, and
a susceptor assembly configured to inductively heat the aerosol-forming substrate under influence of an alternating magnetic field, the susceptor assembly comprising a first susceptor and a second susceptor,
wherein the first susceptor comprises a first susceptor material having a positive temperature coefficient of resistance, and
wherein the second susceptor comprises a second ferromagnetic or ferrimagnetic susceptor material having a negative temperature coefficient of resistance.
