1. A susceptor assembly configured to inductively heat an aerosol-forming substrate under influence of an alternating magnetic field, the susceptor assembly comprising:
a first susceptor including a first susceptor material and a second susceptor including a second susceptor material,
wherein the first and the second susceptor materials are chosen such that during pre-heating of the susceptor assembly starting at room temperature a resistance-over-temperature profile of the susceptor assembly has a minimum value of resistance in a temperature range of ±5 degree Celsius around a Curie temperature of the second susceptor material.
