对于两个铁磁体间的耦合，Ruderman-Kittel [C. Kittel，Quantum Theory of Solids（Wiley，纽约，1963）]理论给出了一个表达式，该表达式作为激光器厚度的函数振荡，并作为厚度的平方倒数渐近地减小。 前因子与电子密度无关。
For the coupling of two ferromagnets separated by a nonmagnetic layer, the Ruderman-Kittel [C. Kittel, Quantum Theory of Solids (Wiley, New York, 1963)] theory gives an expression which oscillates as a function of the thickness of the laser and asymptotically decreases as the reciprocal square of the thickness. The prefactor is independent of the electron density.
