MgCNi3 is a non-oxide perovskite which is both superconducting and ferromagnetic. Here MgCxNi3 is encapsulated in carbon nanoflasks via a chemical method. Magnetic susceptibility measurements indicate the occluded MgCNi3 exhibits a superconducting transition with a critical temperature of 7 K (see Figure).
