What is Enhancement of low-field magnetoresistance in Ce doped manganite Sm0.55Sr0.45MnO3 about?
We report on the magnetization, resistivity and magnetoresistance measurements on polycrystalline samples of Sm 0.55 Sr 0.452x Ce x MnO 3 (x 1⁄4 0 and 0.05). Substitution of Ce(x 1⁄4 0.05) reduced the para -ferromagnetic transition from , 140 K (x 1⁄4 0) to ,90 K. For x 1⁄4 0, the colossal magnetoresistance (CMR) (2 100(r B 2 r 0 )/r 0 ) effect of 55% (143 K) was observed in a field of 0.6 Oe. On the other hand, for the x 1⁄4 0.05 sample, at 93 K, the CMR effect which was 32% in the field of 65 Oe increased to 87% in the field of 0.6 T. Our data rule out grain boundary effects as the principal cause but point out the applicability of the phase separation model.
