    Abstract: Apparatuses, systems, and methods are disclosed related to heat assisted magnetic recording. According to one embodiment, an apparatus that includes a heat sink region and a near field transducer region is disclosed. The near field transducer region is thermally coupled to the heat sink region. At least one of the heat sink region and the near field transducer region includes both an inner core and an outer shell. The inner core can be comprised of a non-plasmonic material and the outer shell can be comprised of a plasmonic material. In further embodiments, the inner core is comprised of a material having a relatively higher electron-phonon coupling constant and the outer shell is comprised of a material having a relatively lower electron-phonon coupling constant.
