Abstract
The conductivity and magnetoresistance in a magnetic field of 0.5 T were st udied for the first time in fused samples of a La0.67Ca0.33MnO3 - alpha com position with variable oxygen nonstoichiometry (0.3 greater than or equal t o alpha greater than or equal to 0) modified by exposure to H-2, H2O vapor, and high vacuum (10(-4) Pa).
