Amorphous BaB6 films synthesized by pulsed laser deposition show ferromagnetic-like signals for substrate temperatures in the range 450–550 °C. The magnetization is virtually anhysteretic, isotropic, and independent of temperature down to 4 K. Less than 4.5% of the volume fraction of the films is magnetically ordered, consistent with models where the magnetism is due to defects, interfaces, or grain boundaries.
