Iron nuclei are the most abundant heavy component of cosmic rays and provide critical insight into their astrophysical origin and propagation. Ground-based IACT telescopes have demonstrated the effectiveness of using the direct Cherenkov light emission of heavy atomic nuclei high-up in the atmosphere for measuring the iron spectrum in the multi-TeV energy range. Building on previous results from H.E.S.S. and VERITAS, we present a measurement of the cosmic-ray iron spectrum above 10 TeV using the MAGIC telescopes. By detecting early Cherenkov emission prior to shower development from primary iron nuclei, we achieve effective separation from lighter elements. Our results are consistent with existing measurements.
