It is well known that the annealing process plays a key role in tuning properties of Fe-based amorphous soft magnetic alloys. However, optimal for particular alloy often difficult to determine. Here, Fe81.4B13.2C2.8Si1.8P0.8 and Fe82.2B12.4C2.8Si1.8P0.8 alloys (denoted as Fe81.4 Fe82.2) were prepared systematically study effects temperature time on properties. The results show optimum ranges Fe82.2 623 K 653 593 K, their coercivity (Hc) values only 2.0–2.5 A/m 1.3–2.7 A/m, respectively....
Magnetic impurities are crucial for probing spin-polarized topological surface states. Scanning tunneling microscopy (STM) studies of Fe on the Bi${}_{2}$Te${}_{3}$(111) preformed and unveil distinct impurity structures unknown origin which exhibit temperature-dependent characteristics. Using density functional theory with spin-orbit coupling, we show that prefers highly coordinated subsurface configurations. By comparing simulated STM images can explain experimental results both...
The molecular beam epitaxy growth of topological insulator Bi2Te3 thin films on Si(111) substrates has been investigated in situ by low-energy electron microscopy. crystal structure and surface morphology during were directly revealed, which enables us to identify the optimal conditions for single crystalline films. formation is preceded several structures, including a wetting layer Te/Bi-terminated Si(111)-1×1 reconstruction. Raman scattering spectra AFM measurements indicate that, under...
