We report the growth of films of the intrinsic ferromagnetic semiconductor NdN, and an investigation of their optical and transport properties. There is clear evidence of a strong anomalous Hall effect as expected from a 4f conduction channel, supported by an optical absorption into a 4f or 4f/5d hybridized tail at the base of the conduction band. The results reveal a heavy-fermion 4f/5d band lying where it can be occupied at controllable levels with nitrogen-vacancy donors.
