摘要： The present disclosure relates to an aerosol-generating device for generating an aerosol by inductive heating of an aerosol-forming substrate. The device comprises a device housing comprising a cavity configured for removably receiving the aerosol-forming substrate to be heated. The device further comprises an inductive heating arrangement comprising at least one induction coil for generating a varying magnetic field within the cavity, wherein the induction coil is arranged around at least a portion of the receiving cavity. In addition, the device comprises a flux concentrator arranged around at least a portion of the induction coil and configured to distort the varying magnetic field of the at least one inductive heating arrangement towards the cavity during use of the device. The flux concentrator comprise a multi-layer flux concentrator foil having at least one magnetic layer laminated with at least a first support layer, wherein the magnetic layer comprises a plurality of separated fragments of a soft magnetic alloy. The disclosure further relates to an aerosol-generating system comprising such a device and an aerosol-generating article, wherein the article comprises the aerosol-forming substrate to be heated. Furthermore, the pr3esent disclosure relates to a method for manufacturing a multi-layer flux concentrator foil of such a device.
