We have synthesized by sol-gel method La(0.54)Ho(0.11)Ca(1-x)Na(x)Mn(1-y)Cr(y)O(3) magnetoresistive bulk manganites. The samples contain only a perovskite phase. The substitution of Mn with Cr led to a strengthening of the metallic ferromagnetic phase. An increase of Curie temperature with Cr concentration was observed, for y < 0.2.
