Abstract
We present a study of the temperature variation of the interlayer coupling strength of antiferromagnetically coupled La2/3Ba1/3MnO3/LaNiO3 heterostruc tures. No drastic decrease in the coupling strength was observed up to the Curie point of the manganite. This behavior suggests that the spin polariza tion of the carriers persists to high temperatures.
