We report on Ag and Cu doping in MgB 2 thick films using amorphous Ag-and Cu-impurity layers with various thicknesses, 4, 8, 16, and 32 nm. Firstly, Ag-and Cu-impurity layers were deposited on Al 2 O 3 (0 0 0 1) substrates at room temperature by using pulsed laser deposition system. Subsequently MgB
