Abstract Studying the vortex properties in high-Tc superconductors is crucial for understanding the high temperature superconducting mechanism. However, until now, only few vortex studies have been performed in 1111-type iron-based superconductors due to their smaller-sized single crystals. In this study, we have synthesized the millimeter-sized CaFe0.89Co0.11AsF single crystals by self-flux method. Three dimensional vortex nature was confirmed in the thermally activated flux flow region. Second magnetization peak was observed on the isothermal magnetization curves. Meanwhile, the dominated role of the normal point pinning was also confirmed. Finally, the various phase boundaries of the vortex were determined based on the analysis of the resistivity and magnetization data, and a complete vortex phase diagram of CaFe0.89Co0.11AsF single crystals was established.
