Magnetic aftereffects in CoFeB/Ta/CoFeB spin valves of large area

Abstract: Magnetic aftereffect measurements on a synthetic antiferromagnet with strong perpendicular anisotropy are presented. Two types of magnetic transitions are observed in the CoFeB/Ta/CoFeB bilayer where the two ferromagnetic CoFeB layers are antiferromagnetically coupled: the transition from a parallel to an antiparallel CoFeB layers magnetization alignment and the transition between two possible antiparallel magnetization states. Magnetic relaxation measurements show a complete reversal in the case of the transi… Show more

“…The magnetic properties of platforms I and II , as well as the interlayer exchange interaction and anisotropy of each layer, were accurately determined as per refs , . A cross-sectional structure and chemical analysis were performed with a transmission electron microscope (TEM), equipped with an energy-dispersive X-ray spectroscopy (EDX) analyzer . Platforms I and II were grown on a GaAs substrate by high vacuum magnetron sputtering .…”

“…Из рис. 1 видно, что наилучшей аппроксимирующей функцией является функция вида (7) (релаксация Колмогорова−Аврами−Фатуззо), так как среднеквадратичное отклонение (СКО) наиболее близко к единице [16]. Для тонких пленок размагничивание является результатом разворота спинов, а также примыкающих к ним спинов за счет энергии обмена малой дальности, что представляет собой механизм зарождения доменов обратной намагниченности или нуклеацию.…”
