制备了具有可调自旋势的磁性层和磁性层交替的自旋超晶格。我们发现，ZnSe/Zn 0.99 Fe 0.01 Se系统，其中场诱导的自旋分裂的价带和导带可以变得比剩余零场电位大得多，表现出自旋超晶格行为。低温磁反射实验已经被用来研究这些结构的性质，通过场相关的自旋分裂和跃迁强度验证它们实际上是真正的自旋超晶格
Spin superlattices with alternating nonmagnetic and magnetic layers, in which a tunable spin-dependent potential exists, have been fabricated. We show that the ZnSe/Zn 0.99 Fe 0.01 Se system, in which field-induced spin splitting in both valence and conduction bands can become much larger than the residual zero-field potentials, exhibits spin superlattice behavior. Low-temperature magnetoreflectance experiments have been used to investigate the nature of these structures, verifying through field-dependent spin splittings and transition strengths that they are in fact true spin superlattices
