It was particularly observed that, with increasing fraction of Q〓 mode Jahn-Teller distortion and decreasing of that of Q〓 mode in the CO state, the magnetic structure evolves from CE-type to C-type, orbital ordering from 3d〓/3d〓 to 3d〓, and crystal structure from tetragonally compressed to tetragonally elongated orthorhombic.

特别是，我们发现〓在电荷有序态下随着Ca〓离子掺杂量从x=0.5增大到x=0.75，合作Jahn-Teller晶格畸变的畸变模式从Q〓模式逐渐转变到Q〓模式，这种晶格畸变模式的转变直接导致了电荷有序态下的磁结构从CE-型转变到C-型，轨道序从3d〓/3d〓转变到3d〓，晶体结构从压缩的正交对称性转变到拉伸的正交对称性。

Experimentally, multi-pores are observed on leukocyte lysed with 3D electrodes and just single pore with planar electrodes. This is believed to be due to more uniform electric field of 3D electrodes than that of planar electrodes. Intracellular elements are extracted through the membrane as observed by increased intensity of Trypan blue when diluted by saline solution. We also demonstrate the lysing percentages at same flow velocity to explain the performance of 3D electrode is superior to that of planar electrode.
