| Research Abstract |
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.
