Abstract

Magnetic properties and giant magneto-impedance (GMI) effects of Fe73.5CU1Nb3Si13.5B9 Single layered films and sandwiched films using Cu or Ag as thecentral layer prepared by radio frequency sputtering are investigated. Theas-deposited single layered films are in amorphous state. The domain structures of single layered films annealed at 380 degrees C show that the filmsare in nanocrystalline state with homogeneous magnetization. The samples possess excellent soft magnetic properties and have the maximum values of GMI effects, the maximum GMI ratios are 18% and 14% in longitudinal and transverse fields, respectively, at 13 MHz. Sandwiched films in the as-depositedstate possess large GMI effects, the maximum GMI ratios of sandwiched films with a Cu central layer are 32% and 11% for longitudinal and transverse cases, respectively, and those of sandwiched films with a Ag central layer are 47% and 57% for longitudinal and transverse cases, respectively. Sandwiched films using Cu as the inner layer annealed at 250 degrees C exhibit large magneto-inductance effect at low frequencies. The maximum magneto-inductance ratio is 1733% at 100 kHz.
