1. A susceptor assembly for inductively heating an aerosol-forming substrate under an influence of an alternating magnetic field, the susceptor assembly comprising:
one or more composite susceptor particles,
wherein each one of the one or more composite susceptor particles comprises a particle core and a particle shell entirely encapsulating the particle core,
wherein the particle core comprises or is made of a ferromagnetic or ferrimagnetic core material having a relative magnetic permeability of at least 200 for frequencies up to 10 kHz at a temperature of 20 degrees Celsius, and
wherein the particle shell comprises or is made of an electrically conductive shell material.
