This paper reports on highly (001)-textured polycrystalline CoFeB/MgAl2O4/CoFeB magnetic tunnel junctions with a large tunnel magnetoresistance over 240% using sputtering on an amorphous Si/SiO2 substrate. This result demonstrates the industrial viability of a spinel-based barrier for spintronic application.
