Research Abstract

To promote integration of 'spintronics' and 'the silicon technology', we are focusing on the actualization of a highly effective spin-injection in the silicon-based device with the aims of "Development of silicon-based ferromagnets", "Demonstration of the spin-injection in ferromagnetic metal / silicon heterostructures". We have succeeded in showing that γ'-Fe4N possesses the high spin polarization (0.59) and the large magnetic moment (2.45μB/Fe). The successful operation of epitaxial CaF_2/Fe_3Si/CaF_2 ferromagnetic resonant tunneling diode was also demonstrated.
