The crystal structure was studied by means of X-ray diffraction,magnetic disaccommodation measurements were carry out with a computer aided system based on a LCR bridge.

X射线衍射仪对粉末样品的结构进行了观,磁落量机辅助系统的阻抗自动量仪(LCR电桥)来完成。

For electrical properties of MOS capacitors, the C-V curves were obtained by LCR meter (HP4284A), and picoampere meter (HP4140B) was used to measure the J-V curves.

另外以电感电容电阻量仪(HP4284A)进行C-V曲线量；以微安培量仪(HP4140B)进行J-V曲线量。
