Abstract
The paper presents investigations of magnetic transport properties of prosp ective materials for fabricating magnetic field transducers, namely, bulk p olycrystalline manganites La(1-x)A(x)MnO(3) (here A = Sr, Ba, or Pb, and 0. 15<x<0.55) over a temperature range of 260-300 K. The nonlinearity of the m agnetoresistance of these materials as a function of magnetic field intensi ty has been studied at room temperature. Among the materials investigated i n the given temperature range, the composition La0.60Sr0.40MnO3 is most sus ceptible to the applied magnetic field, and the nonlinearity of its charact eristic is minimal.
