Description/AbstractA polycrystalline manganite with spectacular magnetoresistive properties, Pr{sub 0.7}Sr{sub 0.05}Ca{sub 0.25}MnO{sub 3{minus}{delta}} has been synthesized. This perovskite-type phase exhibits a resistance variation up to 2.5 x 10{minus}7% at 85 K with {mu}{sub 0}H = 5 T, i.e., one order of magnitude larger than has been observed on the best manganite thin films to date. The size of the interpolated cations, in addition to the mixed valence Mn(III)-Mn(IV), is a crucial parameter for the GMR effect. A route to the utilization of manganite perovskites for device applications is thereby opened.
