结果表明，在与超导体边界附近的铁磁金属中，能量接近费米能量 EF 的局部态密度具有类似于库珀桶衰变的阻尼振荡行为。密度。然而，在能量 E-F+/-I（其中 I 是铁磁体中的交换场）下，衰减长度急剧增加，邻近效应变成长程效应。
It is demonstrated that in a ferromagnetic metal near the boundary with a superconductor the local density of states at energies close to the Fermi energy EF has a damped-oscillatory behavior similar to the decaying of the Cooper's pail. density. However at energies E-F+/-I (where I is the exchange field in the ferromagnet) the decaying length is strongly increased and the proximity effect becomes a long-ranged one.
