The mixed valence manganite CaMn.SUP.7 O.SUP.12 system hasa modulated magnetic ordering below 90 K which gives magnetic satellite reflection at Qó0.2 A.SUB.-1. The results ofsmall-angle neutron scattering (SANS) measurements on polycristaline CaMn.SUP.7 O.SUP.12 with and without external magnetic fields are discussed. It was found that near 50 K there is a second magnetic phase transititon connected witha splitting of the stellite reflection. The Q.SUP.MAX positions, intensities and half-widths of the reflections depend on temperature. The influence of external magnetic fieldon the magnetic ordering is also discussed.
