PERPENDICULAR ELECTRICAL-CONDUCTION IN CU MN MULTILAYER FILMS AT LOW-TEMPERATURES/

The electrical resistivity and the temperature coefficient of the resi stance (TCR) of Cu/Mn multilayer films have been studied in the temper ature range 28-303 K. Two sets of films are investigated, one with a c onstant number of double layers and increasing bilayer wavelength (LAM BDA) in the range 4-12 nm, and the other with constant LAMBDA and vary ing number of double layers (n) in the range 5-30. The bilayer wavelen gth dependence of the room temperature resistivity (rho(RT)) and the T CR exhibit an oscillatory behaviour.
