Abstract
The effect of oxygen isotope substitution on the properties of Pr0.5Ca0.5Mn1 − x Cr x O3 manganites (x = 0, 0.02, 0.05) have been studied. The introduction of chromium favors (i) the decomposition of a charge-ordered state and (ii) the appearance of a ferromagnetic metallic phase in Pr0.5Ca0.5Mn1 − x Cr x 16–18O3. The isotope substitution 16O → 18O leads to a decrease in the content of the ferromagnetic phase, an increase in the charge-ordering transition temperature (T CO), and a decrease in the ferromagnetic transition temperature (T FM). The isotope mass exponent is evaluated.
