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.

用X射线衍射仪对粉末样品的结构观,磁导率减落用计算机辅助系统的阻抗自动仪(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.

另外电感电容电阻计仪(HP4284A)C-V曲线；安培计仪(HP4140B)J-V曲线。
