초록
Magnetic tunnel junctions (MTJs) comprising amorphous Co70.5Fe4.5Si15B10, possessing low saturation magnetization of 560 emu/cm(3), as a free layer have been investigated. The switching behaviours were confirmed for the micrometer-sized elements experimentally, using the scanning magneto-optical Kerr effect (scanning MOKE). A micromagnetic modelling study was also carried out for the submicrometer-sized elements. By using either a CoFeSiB single or a synthetic antiferromagnetic free-layer structure, the magnetization switching field became much lower than conventionally used CoFe free layered MTJs.
