%X Thick MgB2 (magnesium diborate) films, ∼ 10 μm, with Tc (onset) = 39.4 K and Tc (zero) = 39.2 K have been successfully grown on a stainless steel substrate using a technique called hybrid physical-chemical deposition (HPCVD). The deposition rate is high, ∼ 6.7 nm /s. The X-ray diffraction (XRD) indicates that it is highly (101) and c-axis oriented. The scanning electron microscope (SEM) images demonstrate that the film grown is in island-mode . The uniform superconducting phase in the film is shown by the M-T measure-ment.
