  • Boron diffusion in magnetic tunnel junctions with MgO (001) barriers and CoFeB electrodes 

    RODE, KARSTEN; FAULKNER, COLM; BOESE, MARKUS; COEY, JOHN MICHAEL DAVID; KURT, HUSEYIN; OGUZ, KAAN (2010)
    Boron diffusion out of the CoFeB layers in model systems with thick CoFeB and MgO layers grown by radiofrequency sputtering or electron-beam evaporation and in MgO-based magnetic tunnel junctions (MTJs) is probed after ...
  • Low magnetisation alloys for in-plane spin transfer torque devices 

    COEY, JOHN MICHAEL DAVID; OGUZ, KAAN (2012)
    Magnetic properties of thin films of three in-plane alloy systems, namely, Co40Ni40?xCrxB20, Co40Fe40?xNixB20, and Co40Fe40?xCrxB20 are investigated with a view to reducing the critical current density (jc ) for spin ...
  • Perpendicular Magnetic Anisotropy in CoFeB/Pd Bilayers 

    RODE, KARSTEN; KURT, HUSEYIN; OGUZ, KAAN; COEY, JOHN MICHAEL DAVID; FOWLEY, CIARAN (2010)
    Perpendicular magnetic anisotropy is observed in ultrathin (0.6 nm) amorphous Co40Fe40B20 when sputtered on an MgO (001) buffer layer and capped with Pd. The layers are superparamagnetic with a blocking temperature of ...
