Abstract

Pyrite-Type cobalt disulfide (CoS2), which is one among other stable cobalt sulfide phases, exhibits interesting electronic and magnetic properties. Herein, we demonstrate a tailored metalorganic chemical vapor deposition (MOCVD) pathway for the growth of high-quality ferromagnetic CoS2thin films. The influence of CVD process parameters on growth and quality of the films was investigated by complementary analyses. Superconducting quantum interference device (SQUID) measurements confirmed the existence of pure CoS2with a magnetic moment of 0.85 μBand a Curie temperature of 128(5) K. Our findings could pave the way for large-Area CoS2to be used for different technological applications.
