The crystal and magnetic structure of (La0.70Ca0.30)(CryMn1-y)O3 for y =0.70, 0.50 and 0.15 has been investigated using neutron powder diffraction. Thethree samples crystallize in the Pnma space group at both 290 K and 5 K andexhibit different magnetic structures at low temperature. In(La0.70Ca0.30)(Cr0.70Mn0.30)O3, antiferromagnetic order with a propagationvector k = 0 sets in. The magnetic structure is Gx, i.e. of the G-type withspins parallel to the a-axis. On the basis of our Rietveld refinement and theavailable magnetisation data, we speculate that only Cr3+ spins order, whereasMn4+ act as a random magnetic impurity. In (La0.70Ca0.30)(Cr0.50Mn0.50)O3 thespin order is still of type Gx, although the net magnetic moment is smaller. Noevidence for magnetic order of the Mn ions is observed. Finally, in(La0.70Ca0.30)(Cr0.15Mn0.85)O3 a ferromagnetic ordering of the Mn spins takesplace, whereas the Cr3+ ions act as random magnetic impurities with randomlyoriented spins.
