ABSTRACT
We report on growth and magnetic properties of exchange-coupled (111)-L10 FePt hard/CoFeTaB soft magnetic metallic glass bilayered structure processed at lower temperature (∼400 °C). Single phaselike hysteresis loops with tailorable coercivity (<8.2 kOe) in out of plane direction are obtained. The magnetization switching mechanism is identified as domain wall assisted. In views of excellent nanofabrication abilities of metallic glass thin film and the ability to grow preferred oriented L10 FePt, the present bilayered structure is very promising for the fabrication of high density bit—patterned magnetic recording media and other spintronic devices.

    Many works have demonstrated perpendicular magnetic anisotropy in CoFe2O4-BiFeO3 (CFO-BFO) composites, which is commonly believed to originate from out-of-plane compressive strain in the CFO pillars due to the lattice mismatch with the BFO matrix. Others have shown that the pillar-matrix...
