Substantial reduction in coercivity of perpendicular CoPt/FePt graded films with near-atomic flatness on glass substrates

Preventing dewetting during rapid-thermal annealing of FePt films with enhanced L10 ordering by introducing Ag cap-layers

“…Recently, it has been also applied to various magnetic materials, such as soft magnetic materials, spintronic devices, recording media and high energy density permanent magnets [3]. RTA has also been considered as a potential technique for the fabrication of (001) textured FePt films on amorphous substrates [4][5][6][7][8][9][10][11][12][13]. In our previous study, we demonstrated that a high heating rate can induce a strong tensile stress, which energetically favoring the grain growth of (001) [8].…”

Effect of hydrogen plasma implantation on the micro-structure and magnetic properties of hcp-Co80 57Fe4Ir16 thin films*

“…Soft magnetic thin films (SMTFs) with adjustable high-frequency magnetic properties are highly desirable due to their wide range of applications, such as film inductors, [1,2] micro-transformers, [3] and microwave noise filters, [4,5] etc. Various methods have been proposed for the development of these SMTFs, such as chemical substitution, [6][7][8][9][10] high temperature and high magnetic field annealing, [11][12][13][14][15] crystal texture, [16] and hydrogen ion implantation, [17][18][19][20] etc. Among these methods, hydrogen implantation has been shown to be a powerful platform to tailor the physical properties of both transition metal oxides and various kinds of metal alloys.…”

A Novel NDT Method for Coercive Force of Grain-Oriented Electrical Steel Applied in Cigarette Machines

“…The lower the coercive force is, the more sensitive the response is in the low magnetic field [8]. The coercive force is related to the external magnetic field strength, which is a point on the magnetic hysteresis loop, which reflects the hysteresis characteristics of the material [9][10][11]. Coercive force is one main magnetic property of grainoriented electrical steel, and the performance of the coercive force influences other magnetic parameters, further affecting the electromagnetic properties of the electrical products [12].…”
