玻色子体系中的非平衡输运过程研究是极具挑战性的工作.磁振子是玻色子,具有与电子等费米子截然不同的自旋输运行为.本文以钇铁石榴石(YIG)铁磁绝缘体为研究对象,聚焦影响稳态下YIG中磁振子非平衡输运过程的关键因素.通过将具有非零化学势μm的玻色-爱因斯坦统计函数引入到玻尔兹曼输运方程中,获得了以为幂次的输运方程严格解析表达式(当α(=-μm/(k_(b)T))<1时).结果显示,当α<<1时,我们得到了与以往研究不同的化学势μm与非平衡粒子浓度δn_(m)之间的非线性关系δn_(m)∝-α^(1/2)α-(-μm)^(1/2)α;较大时,则还须考虑其高阶项.正因这种非线性关系,导致磁振子扩散方程显著不同于电子自旋扩散特性,其由线性微分方程演变为更复杂的非线性微分方程.本文重点研究了在两种极端温度梯度(即■T~1K/mm和10^(4)K/mm)下非平衡磁振子浓度δn_(m)和化学势μm的空间分布,它们分别对应于μm的值约为-0.1μeV和-6.2meV,均满足前提条件α<1.在远离平衡态的大温度梯度分布下,本文理论计算与实验结果吻合很好.这些理论研究结果将加深人们对铁磁绝缘体中磁振子非平衡输运行为的认识.

Formation of β’ phase in long-period stacking ordered(LPSO) structures in an Mg;Co;Y;(at.%) alloy after aging at 200 °C for 24 h or electron beam(Eb) irradiation has been studied by high-angle annular dark-field scanning transmission electron microscopy(HAADFSTEM). β’ phase was precipitated only in the Mg matrix but not in LPSO structures after aging at 200 °C for 24 h. LPSO structure containing stacking defects transforms into the β’-long phase during Eb irradiation, which plays a key role in accelerating solute atoms’ diffusion. New complex β’(LPSO) structures formed in the alloy after Eb irradiation, such as β’(12 H) structure with an orthorhombic lattice(Mg;Y, Cmcm,a = 2 _(a0)= 0.642 nm, b=4√3_(a0), c = 6 _(c0)= 3.12 nm).
