(57)Fe Mossbauer spectroscopic studies of Co(2)Mn(1-xCex)Fe(x) Al based
Heusler compounds are presented. The cubic structure type was found for
all samples of the series in XRD studies. However, a mixture of the
cubic B2 and L2(1) structure types are not unambiguously distinguished
by XRD. The present study gives evidence for a mixture of the L2(1)
structure with additions of a large amount of B2 like disorder. The
isomer shifts and hyperfine magnetic fields on (57)Fe atoms are compared
with theoretical values from CPA calculations.
