The magnetotransport properties of single crystal trilayers 60 Aa Co{sub 2}MnGe/NM/30Aa Co{sub 2}MnGe where NM is a nonmagnetic spacer material has been studied. The samples were grown by molecular beam epitaxy on GaAs (001) substrates. The 2 to 1 ratios in thickness of the Co{sub 2}MnGe layers allows for the easy determination of which ferromagnetic layers have switched during magnetometry measurements. A weak 90{degree} coupling has been observed in trilayers with either a Mn or a V spacer layer. In these coupled films a giant magnetoresistance type magnetoresistance of less than 1% has been measured at room temperature. {copyright} 2001 American Institute of Physics.
