Abstract: The EPR spectra and conductivity of La$_{1-x}$Sr$_x$Mn$_{0.925}$Zn$_{0.075}$O$_3$ ($x$ = 0.075, 0.095, 0.115) ceramics with a crystal structure examined by X-ray diffraction have been studied. At $x$ = 0.095, a pronounced magnetic-field dependence of the electrical resistivity has been revealed in the temperature range from 190 to 228 K. For samples with $x$ = 0.075 and 0.115, no similar behavior has been observed. The EPR linewidth linearly increases with increasing temperature in the range from 180 to 380 K for all the samples; the slope decreases as the strontium concentration increases.
