Symmetry of wavefunctions at Fe/MgO magnetic tunneling junction (MTJ) interfaces was measured by magnetic Compton profile (MCP) measurements. Theoretical calculations by the DV-Xα method for Fe/MgO MTJ were compared with the MCP measurements. The symmetry of wavefunctions is conserved at the MTJ interfaces. Fe oxidization at the MTJ interface deforms the symmetry of wavefunction.

Fe/Mgo磁性隧道连接处（MTJ）接口处波型的对称性是通过磁性Compton曲线（MCP）测量测量的。将Fe/MGO MTJ的DV-Xα方法与MCP测量进行了比较。波形的对称性在MTJ界面处保守。 MTJ界面处的Fe氧化变形可变形波功能的对称性。
