Abstract Bulk nano-scale multilayers have been prepared by repeated pressing-rolling the initially macroscopically thick layered sample. The SEM and TEM observations revealed that the final layer thickness in the regular laminates is about 10 nm. The Fe/Cu multilayers exhibited a clear magnetoresistance (MR) ratio at 77 K. The tensile strength is over 1500 MPa and its elongation is about 0.8% at room temperature.
