ABSTRACT

The electrical resistance of polycrystalline samples of the compound La0.875Sr0.125Mn0.975Zn0.025O3, La0.90Sr0.10Mn0.95Zn0.05O3, La0.95Sr0.05Mn0.90Zn0.10O3, La0.975Sr0.025Mn0.875Zn0.125O3, La0.855Sr0.145Mn0.975Zn0.025O3, La0.88Sr0.12Mn0.95Zn0.05O3, La0.93Sr0.07Mn0.90Zn0.10O3 was studied in the temperature range 80-300 K in the absence of a magnetic field and in a magnetic field of 9.2 kOe. The electrical conductivity of all compounds in the investigated temperature range (80-300 K) is semiconductor. It is established that for all structural components, the influence of the magnetic field on the resistance decreases with increasing temperature. It is believed that with increasing temperature, the mobility of carriers decreases, which weakens the influence of the magnetic field on the carriers.
