摘要：
The exchange of antiferromagnetic spin fluctuations leads to highly anisotropic pairing interactions with attractive as well as repulsive contributions. Using these pairing interactions, the order parameter DELTA (k over arrow pointing right, T) is calculated for different quasiparticle dispersion relations and band fillings. The effect of specific momentum dependences of the order parameter on the tunneling density of states and the size of the apparent gap is discussed.
