Abstract:
We investigate the evolution of spin polarization, spontaneous Hall angle (SHA), saturation magnetization,
and Curie temperature of B2-ordered Fe 60 Al 40 thin films under varying antisite disorder, induced by Ne+-ion
irradiation. The spin polarization increases monotonically as a function of ion fluence. A relatively high polar-
ization of 46% and a SHA of 3.1% are achieved on 40 nm films irradiated with 2 × 10 16 ions/cm 2 at 30 keV. An
interesting divergence in the trends of the magnetization and SHA is observed for low disorder concentrations.
The high spin polarization and its broad tunability range make ion-irradiated Fe 60 Al 40 a promising material for
application in spin electronic devices.
