Description
The surfaces of Sb2Te3 topological insulator crystals were implanted using a 40 keV chromium ion beam at the Centre for Accelerator Science, ANSTO. The resulting chemical structure was studied using atomic-resolution transmission electron microscopy and soft X-ray absorption spectroscopy. A thin magnetic crystalline region is formed near the surface. A uniform valence state of Cr3+ is detected, with no evidence of metallic clustering. Superparamagnetic behaviour was detected up to 300 K.
