Matching second-order classical and 1-loop quantum tensor power spectra in de Sitter spacetime

A. Hauser, M. Laine

Large corrections to the inflationary tensor power spectrum have been speculated to emerge either as second-order scalar-induced classical effects, or as 1-loop quantum corrections…

Comment on `Oxygen vacancy-induced magnetic moment in edge-sharing CuO $_{2}$ chains of Li $_{2}$ CuO $_{2}$ '

R. O. Kuzian, R. Klingeler, W. E. A. Lorenz +23

In a recent work devoted to the magnetism of Li $_{2}$ CuO $_{2}$ , Shu et al. [New J. Phys. 19 (2017) 023026] have proposed a "simplified" unfrustrated microscopic model that differs…

Tailoring properties of Heusler alloys by elemental substitution and electron counting: (Co $_{2 - I^\pm}$ Mn $_{I^} \pm$ )FeGe, Co $_{2}$ (Fe $_{1 - I^^{2}}$ Mn $_{I^}^{2}$ )Ge, and (Co $_{2 - I^\pm}$ Fe $_{I^} \pm$ )MnGe

R. Mahat, S. Budhathoki, S. Regmi +6

Rational material design by elemental substitution is useful in tailoring materials to have desirable properties. Here we consider three non-equivalent substitutional series based…

Thermodynamics of the frustrated $J_{1}$ - $J_{2}$ Heisenberg ferromagnet on the body-centered cubic lattice with arbitrary spin

P. MÃ¼ller, J. Richter, A. Hauser +1

We use the spin-rotation-invariant Green's function method as well as the high-temperature expansion to discuss the thermodynamic properties of the frustrated spin- $S$ $J_{1}$ -$J_{…

Long-range FMR driven spin pumping through a nonmagnetic insulator

Y. Pu, H. L. Wang, C. H. Du +8

Ferromagnetic resonance (FMR) driven spin pumping is an emerging technique for injection of a pure spin current from a ferromagnet (FM) into a non-magnetic (NM) material without an…
