In the process of the surface modification diamond with layered ferrimagnetism, diamond 110 surface was heated through the diamond body by condenced infrared rays irradiation forcused on manganese powder at the diamond interface. The modified diamond surface at 450 degree Celsius had a metallic luster, and in the case of modified at 550 degree Celsius, the modified diamond surface had some finges. As a result, The Mn7C3 and Mn5C2 peakes were observed on the X-ray diffraction pattern for the dimond 110 specimen heated at 550 celsius degree. By a Hall effect device, the magnetic flux of modified diaond were measured at room temperature and low temperature(-3 degree Celsius). However, the measured values were not stable. From the results of VSM measurement, the modified diamond had saturated mangetization of 20 micron emu at room temperature.

在层状铁磁性表面改性金刚石的过程中，通过聚焦在金刚石界面处锰粉的浓缩红外线照射，使金刚石110表面通过金刚石本体加热。在450摄氏度下修饰的金刚石表面有金属光泽，在550摄氏度下修饰的金刚石表面有一些指状。结果表明，在550℃加热下，金刚石110样品的x射线衍射图上出现了Mn7C3和Mn5C2峰。利用霍尔效应装置测量了改性金刚石在室温和低温（-3℃）下的磁通量。然而，测量值并不稳定。从VSM测量结果来看，改性金刚石在室温下具有20微米鸸鹋的饱和锰化。
