Abstract We find a candidate for new permanent-magnet materials with the 1–16 stoichiometry on basis of first-principles calculations utilizing database. An extremely iron-rich NdFe 16 compound shows exceptionally high saturation magnetization an adequate magnetocrystalline anisotropy energy and Curie temperature. Although it has excessive formation in its binary composition, introducing interstitial light elements into successfully decreases while maintaining superior magnetic properties....
A complex interplay between the crystal structure and electron behavior within borophene renders this material an intriguing 2D system with many of its electronic properties still undiscovered. Experimental insight into those is additionally hampered by limited capabilities established synthesis methods, which in turn inhibits realization potential applications. In multi-method study, photoemission spectroscopies scanning probe techniques complemented theoretical calculations have been used...
Two-monolayer-thick In film with a $\ensuremath{\surd}7\ifmmode\times\else\texttimes\fi{}\ensuremath{\surd}3$-rect structure is known to show superconductivity at 3.18 K on the $\mathrm{Si}(111)7\ifmmode\times\else\texttimes\fi{}7$ substrate. We synthesized $\ensuremath{\surd}7\ifmmode\times\else\texttimes\fi{}\ensuremath{\surd}3$-In-rect $\mathrm{Si}(111)\ensuremath{\surd}3\ifmmode\times\else\texttimes\fi{}\ensuremath{\surd}3\text{\ensuremath{-}}\mathrm{B}$ substrate and found that it also...
We examine the IrO3 desorption from iridium surfaces using first-principles calculations. To investigate out-of-equilibrium adsorption–desorption steps, we estimate temperature dependence of changes in free energy considering molecular excitation. Our result shows that occurs at a specific range. In addition to kinks, identify terrace Ir(111) surface is active for contrast less-close-packed (100) and (110) surfaces. The absence transition state found during process.
