应用变分法研究了极性晶体膜中强耦合磁极化子的性质，给出基态和激发态的系统能量，重点研究了系统处于基态和激发态时的电子－表面声子相互作用能．计算结果表明，在磁场强度一定的条件下（Ｂ＝９Ｔ），电子－表面声子相互作用能随着膜厚的增加而减小；在一定膜厚的条件下（Ｗ＝３ｎｍ），电子－表面声子相互作用能随着磁场强度的增加先增大而后缓慢减小，当Ｂ＝３０Ｔ时，｜Ｖｅ－ＳＯ（１）｜和｜Ｖｅ－ＳＯ（０）｜之间的差最大．
The properties of strongly coupled magnetopolaron in a polar crystal film were studied by using the variational method. The energy of the ground state and the excited state were given. The interaction energies of the electron-surface phonon interaction in the ground state and the excited state were emphatically studied. The calculated results show that the electron-surface phonon interaction decreases with the increase of the film thickness under certain magnetic field strength (B = 9T). Under a certain film thickness (W = 3nm), the electron- The surface phonon interaction can increase first and then decrease slowly with the increase of magnetic field intensity. When B = 30T, the difference between | Ve-SO (1) | and | Ve-SO (0) |
