摘 要：The magnetoresistance (MR) measurements on a naturally occurring multilayer Dy0.4Sm0.6Mn6Ge6 were presented, which is ferrimagnetic below 445 K. In the temperature range below 65 K, MR displays a maximal value around 3 T and above this critical field MR decreases, in the positive direction, with fields up to 5 T. Its upturn may result from the influence of the magnetic field on the Fermi surface. It is also possible that the scattering of the conduction electrons by the nonmagnetic layers Ge becomes dominant at low temperatures.
