论文摘要
我们使用旋转屈光度模型来描述高-TC超导体的CuO $ _2 $飞机。使用大波长方法，我们表明Cu自旋波动的铁磁成分夫妇偶对氧孔产生一种配对相互作用，从而导致超导间隙，其对称性由近相互作用的各向异性确定。我们在平均场近似中计算TC是孔浓度的函数，我们的数值结果与实验非常吻合。
We use the spin-fermion model to describe the CuO$_2$ planes of the high-Tc superconductors. Using a large wavelength approach, we show that the ferromagnetic component of the Cu spin fluctuations couple to the oxygen holes producing a pairing interaction that leads to a superconducting gap whose symmetry is determined by the anisotropy of the Kondo interaction. We calculate Tc as a function of the hole concentration in a mean-field approximation and our numerical results are in good agreement with the experiments.
