Temperature and field dependent magnetic Compton profiles of BixCo2-xMnO4 (x=0 and 0.3) multiferroics are reported. The magnetic Compton profiles and total spin moments are interpreted in terms of Mn/Co-3d contribution. Mn spin moments are found to be dominating in total magnetization whereas a small contribution of Co spin moment couples antiferromagnetically with that from Mn sites. The magnetic Compton data when compared with magnetization data, interestingly, show a reverse trend of orbital magnetic moments which are explained in terms of exchange interaction between the ions at different sites via O2- ions.
