Abstract

We investigate the effect of thin-film Ni deposition on the magnetic phases of bulk CrI3. In pristine CrI3, surface antiferromagnetism coexists with bulk ferromagnetism below 2T . After depositing a 4 nm thick Ni film via E-beam evaporation, field-dependent Raman spectroscopy revealed that, unlike pristine CrI3, the Ni/CrI3 hosts a single magnon branch across all measured fields (0T to 7T), indicating the suppression of the surface antiferromagnetic phase found in pristine CrI3. These results show that metallic thin-film deposition provides an effective route for tuning magnetic phases in magnetic van der Waals materials, with potential spintronics applications.
