Zusammenfassung:	The compound La{sub 0.66}Ba{sub 0.40}Mn{sub 0.61}Fe{sub 0.33}O{sub 3} shows anisotropic magnetic correlations with no long-range order. Specific heat measurements suggest these correlations represent the bulk. Orbital correlations of Mn{sup 3+}e{sub g} electrons, surviving in an environment of largely disordered exchange interactions, are invoked to account for this magnetic state. These results argue in favor of a strain-field mechanism for orbital ordering in manganites.
