Domain state modulation by interfacial diffusion in FePt/FeCo thin films: experimental approach with micromagnetic modelling

“…Recently, Preller et al realized large room temperature coercivity of 1.34 T in polycrystalline FePt/Fe 3 Pt films [22]. FeCo is the best chosen soft ferromagnetic material to couple with FePt due to its high saturation magnetization of 2.4 T [23,24], low anisotropy ∼4 × 10 4 J m −3 [25,26] and high Curie temperature [27,28]. The exchange-coupled FePt/FeCo bilayer thin films are the most stimulating magnetic multilayers in terms of distinctive properties such as large saturation magnetization, high coercivity and hence a high energy product retaining a high thermal stability as well [29,30].…”

Magnetization dynamics and domain reversal in electrodeposited permalloy thin films: impact of thickness and annealing treatment

“…It has also been reported that higher boric acid concentration in the electrolyte baths improved the uniformity of the electrodeposited alloy and the grain size was reduced [47][48][49]. A small amount (0.05 M) of L-ascorbic acid (C 6 H 8 O 6 ) was also added to minimize the oxidation of Fe 2+ ions [33,34,39,50]. After adding all the chemical constituents, the solution underwent stirring at ambient conditions for almost 2 h until a transparent light green solution was obtained.…”

“…Discovering more economical and efficient methods for fabricating thick permalloy films with desired structural and magnetic properties is crucial for industrial applications [16,32]. Electroplating of Fe-Ni alloys have been used from long time for protective coatings, it offers several advantages, including control over alloy composition, fast deposition rates, and cost-effectiveness etc [33][34][35][36][37]. Additionally, the annealing of these electrodeposited films under feasible conditions can further improve the quality and improve the desired properties [14].…”
