Abstract A model is presented to explain the temperature-independent saturating paramagnetic response of some transparent oxides with no unpaired d-electrons. It is based on an array of N surface defect-related electrons with bound states in the gap that can form a coherent mesoscopic many-electron state in response to fluctuations of the zero-point electromagnetic field. Individual electronic orbits expand by 0.083 pm, as in the theory of the Lamb shift, and these expansions add to produce a global volume change. This modifies the energy density in the zero-point electromagnetic field, thereby lowering the energy per electron sufficiently to stabilize a coherent multi-electron state of the two-dimensional system at room temperature. A net magnetic moment can be induced by an applied magnetic field, which mixes coherent ground and excited states, producing a paramagnetic orbital magnetization of magnitude M = M S x 1 + x 2 , where x is proportional to the applied field. Orbital saturation moments per coherent surface electron range from 10 - 3 to 10 - 1 Bohr magnetons.

细观轨道顺磁性；零点能量的作用

摘要 提出了一个模型来解释一些没有未成对 d 电子的透明氧化物的与温度无关的饱和顺磁响应。它基于一系列 N 表面缺陷相关电子，在间隙中具有束缚态，可以响应零点电磁场的波动形成相干的介观多电子态。正如兰姆位移理论中的那样，单个电子轨道会膨胀 0.083 pm，并且这些膨胀会产生全局体积变化。这会改变零点电磁场中的能量密度，从而充分降低每个电子的能量，以在室温下稳定二维系统的相干多电子态。外加磁场可以感应出净磁矩，该磁场混合了相干基态和激发态，产生大小为 M = MS x 1 + x 2 的顺磁轨道磁化强度，其中 x 与施加的场成正比。每个相干表面电子的轨道饱和矩范围从 10 - 3 到 10 - 1 玻尔磁子。
