a Sheet resistance of C30/Tn heterostructures as a function of temperature. The inset shows the activation charge gap of C30/Tn. b Temperature dependence of magnetisation M(T) curves for C30/Tn under field cooling measured by applying an in-plane magnetic field H = 0.1 Tesla. c Magnetic hysteresis loops M(H) measured at 10 K for C30/Tn heterostructures. The saturation magnetisation reaches ~0.9 μB/Co, evidencing the stoichiometric LCO of the C30/T030. The disappearance of FM ordering in the La3Co3O8 and La2Co2O5 indicates an AFM ground state as in their bulk form31, 32.
