Low-field magnetoresistance of Ag-substituted perovskite-type manganites
A series of bulk polycrystalline Nd 1− x Ag x MnO 3 samples were prepared by conventional solid-state reaction processing, for x between 0.1 and 0.5. The structure, magnetism, and magnetoresistance (MR) of the samples are investigated. The X-ray diffraction patterns show that the x=0.1 sample is a s...

3 samples were prepared by conventional solid-state reaction processing, for
x between 0.1 and 0.5. The structure, magnetism, and magnetoresistance (MR) of the samples are investigated. The X-ray diffraction patterns show that the
x=0.1 sample is a single perovskite structure, while
x⩾0.167, samples consist of a ferromagnetic perovskite phase and two nonmagnetic phases, Ag and Mn

3 is enhanced by increasing the composition of Ag. Compared with the sample of
x=0.1, the
x=0.5 sample has a significantly larger value of low-field MR. The enhanced low-field MR is related to the spin-dependent scattering of spin-polarized electrons at the interfaces between the perovskite grains and silver granules. |
