We explore the possibility of exciting spin waves in insulating antiferromagnetic films by injecting spin current at the surface. We analyze both magnetically compensated and uncompensated interfaces. We find that the spin current induced spin-transf

We report a detailed experimental and theoretical study of the electronic structure of Mo _1− _x Re _x random alloys. We have measured electronic band dispersions for clean and hydrogen-covered Mo _1− _x Re _x (110) with x = 0–0.25 using angle-

Simulating order–disorder phase transitions in magnetic materials requires the accurate treatment of both the atomic and magnetic interactions, which span a vast configuration space . Taking FeCo as a prototype system, we demonstrate that this can

Concentrated solid-solution alloys (CSAs) based on 3d transition metals have demonstrated extraordinary mechanical properties and radiation resistance associated with their low stacking fault energies (SFEs). Owing to the intrinsic disorder, SFEs in

We study the K-state phenomenon in the NiCoCr medium-entropy alloy using first-principles techniques jointly with the efficient Wang–Landau Monte Carlo and simulated annealing algorithms. Our theoretical results successfully explain the existence o

The sensitivity in predicting glide behaviour of dislocations has been a long-standing problem in the framework of the Peierls-Nabarro model. The predictions of both the model itself and the analytic formulas based on it are too sensitive to the inpu

The Green function plays an essential role in the Korringa–Kohn–Rostoker(KKR) multiple scattering method . In practice, it is constructed from the regular and irregular solutions of the local Kohn–Sham equation and robust methods exist for sphe

High-entropy alloys constitute a new class of materials whose very existence poses fundamental questions regarding the physical principles underlying their unusual phase stability. Originally thought to be stabilized by the large entropy of mixing as

We report the stacking fault energy (SFE) for a series of face-centered cubic ( fcc ) equiatomic concentrated solid solution alloys (CSAs) derived as subsystems from the NiCoFeCrMn and NiCoFeCrPd high entropy alloys based on ab initio calculations. A
