When in 1920 I resumed my studies of theoretical physics which had long been interrupted by circumstances beyond my control, I was far from the idea that my studies would bring me several years later to receive such a higl and envied prize as that awarded by the Swedish Academy of Sciences each year to a scientist: the Nobel Prize for Physics. What at that time drew me towards theoretical physics was not the hope that such a high distinction

电子自旋的概念是 Pauli在1924年首先提出的。1925年, S.A. Goudsmit和 G Uhlenbeck用它来解释某种元素的光谱精细结构获得成功 Stern和 Gerlaok也以实验直 接证明了电子自旋磁矩的存在。 电子自旋共振( Electron Spin Resonance)缩写为ESR又称顺磁共振( Paramagnetic Resonance它是指处于恒定磁场中的电子自旋磁矩在射频电磁场作用下发生的一种磁 能级间的共振跃迁现象。这种共振跃迁现象只能发生在原子的固有磁矩不为零的顺磁 材料中,称为电子顺磁共振。194年由前苏联的柴伏依斯基首先发现
