Native point defects and impurities in hexagonal boron nitride

L. Weston, D. Wickramaratne, M. Mackoit, A. Alkauskas, and C. G. Van de Walle

Phys. Rev. B 97, 214104 (2018) - Published 18 June, 2018

Hexagonal boron nitride ( $h$ -BN) is a technologically important electronic and dielectric material. Recently, research into this material has intensified due to the discovery of bright single-photon-emitting color centers in the form of point defects, with potential applications in advanced quantum technologies. Despite this technological promise, the defect physics of this material is still largely unexplored. Here, the authors have performed detailed first-principles investigations of the defect properties of $h$ -BN, finding that the defect physics of this material is dictated by impurities, in particular carbon, oxygen, and hydrogen. They show how the defect properties of this material can be selectively engineered by growth or processing conditions. These insights will be fundamental to controlled generation of single-photon emitters and for general defect engineering of this material.

Helical magnetic structure and the anomalous and topological Hall effects in epitaxial B20 ${Fe}_{1 - y} {Co}_{y} Ge$ films

Charles S. Spencer, Jacob Gayles, Nicholas A. Porter, Satoshi Sugimoto, Zabeada Aslam, Christian J. Kinane, Timothy R. Charlton, Frank Freimuth, Stanislav Chadov, Sean Langridge, Jairo Sinova, Claudia Felser, Stefan Blügel, Yuriy Mokrousov, and Christopher H. Marrows

Phys. Rev. B 97, 214406 (2018) - Published 6 June, 2018

Magnetic materials with chiral lattices are known to support chiral spin textures such as skyrmions and chiral bobbers. These give rise to transport properties, intrinsically linked to their nontrivial topology. Here, the authors study epitaxial films of Fe $_{1 - y}$ Co $_{y}$ Ge across the entire range from the well-known chiral magnet FeGe to the nonmagnetic CoGe. The measured magnetic and transport properties are compared with the results of $a b$ $i n i t i o$ electronic structure calculations. Theory and experiment agree on a change in sign of the chiral Dzyaloshinskii-Moriya interaction at $y \sim 0.45$ . Nevertheless, the observed topological Hall effect for neighboring values of $y$ is far larger than theory predicts. This discrepancy points to the need for a deeper understanding of transport in disordered half-metallic chiral magnets.

EDITORS' SUGGESTION

Intrinsic hysteresis due to the surface barrier for chiral solitons in monoaxial chiral helimagnets

M. Shinozaki, Y. Masaki, R. Aoki, Y. Togawa, and Y. Kato

Phys. Rev. B 97, 214413 (2018) - Published 13 June, 2018

Chiral solitons in monoaxial chiral magnets undergo a surface barrier, which is analogous to the Bean-Livingston barrier in type-II superconductors. The authors argue here that the surface barrier is the main mechanism for large hysteresis observed in magnetoresistance (MR) measurements on micrometer-sized samples of CrNb $_{3}$ S $_{6}$ . In the MR hysteresis, a conspicuous jump is observed at the field $H_{b}$ for decreasing fields. Experimental results for $H_{b} \sim 0.4 H_{c}$ (with thermodynamic critical field $H_{c}$ ) and the theoretical result $H_{b} / H_{c} = 4 / π^{2}$ are in good agreement with each other. The surface barrier is regarded as a common property of systems (superconductors, chiral magnets, and chiral liquid crystals) that exhibit continuous transitions of the nucleation type.

Selection rules for cavity-enhanced Brillouin light scattering from magnetostatic modes

J. A. Haigh, N. J. Lambert, S. Sharma, Y. M. Blanter, G. E. W. Bauer, and A. J. Ramsay

Phys. Rev. B 97, 214423 (2018) - Published 20 June, 2018

Brillouin light scattering (BLS) is a useful tool for studying magnons, the elementary excitations of magnetic order. However, this process is typically quite weak. In order to enhance BLS, optical cavity modes, such as the whispering gallery modes in a sphere of transparent magnetic material, can be exploited. Here, the authors study cavity-enhanced BLS from magnons in a range of different magnetostatic modes. The selection rules that govern the process are identified and understood based on recent theoretical predictions (Phys. Rev. B 96, 094412 (2017)). Additional enhancement of BLS can be achieved through the better spatial overlap of higher-order magnetic modes with the optical modes.

Absence of superconductivity in iron polyhydrides at high pressures

Christoph Heil, Giovanni B. Bachelet, and Lilia Boeri

Phys. Rev. B 97, 214510 (2018) - Published 13 June, 2018

The recently reported formation of the new iron polyhydride FeH $_{5}$ at megabar pressures raised hopes about its potential high- $T$ $_{c}$ superconductivity because of an alleged layer of dense metallic hydrogen. Using electronic structure calculations, the present work shows that FeH $_{5}$ displays no conventional superconductivity, since the electronic states at the Fermi level do not exhibit appreciable electron-phonon coupling. Superconductivity may be attained by partially filling empty Fe–H hybrid bands by adding more electrons, but critical temperatures would remain relatively low, because the $d$ -metal bonding, and not the metallic hydrogen, dominates the electrons and phonons involved in the superconducting pairing.

Coexistence of superconductivity and short-range double-stripe spin correlations in Te-vapor annealed ${FeTe}_{1 - x} {Se}_{x}$ ( $x \leq 0.2$ )

Zhijun Xu, J. A. Schneeloch, Ming Yi, Yang Zhao, Masaaki Matsuda, D. M. Pajerowski, Songxue Chi, R. J. Birgeneau, Genda Gu, J. M. Tranquada, and Guangyong Xu

Phys. Rev. B 97, 214511 (2018) - Published 14 June, 2018

The single-stripe antiferromagnetic (SAF) spin correlations found in many iron-based superconductors are believed to be important to the development of superconductivity in these system. By contrast, the double-stripe antiferromagnetic (DSAF) spin correlations are always found to be present in the nonsuperconducting region of Fe $_{1 + y}$ Te $_{1 - x}$ xSe $_{x}$ systems with small $x$ values. Here, the authors study bulk crystals of Fe $_{1 + y}$ Te $_{1 - x}$ Se $_{x}$ with $x$ = 0.1 and 0.2, when superconductivity can be induced by annealing in Te vapor. Inelastic neutron scattering measurements reveal low-energy magnetic excitations consistent with short-range correlations with a mixed single-stripe/double-stripe character. The mixed magnetic character of these superconducting samples does not appear to be trivially explainable by inhomogeneity, and suggest that superconductivity in Fe $_{1 + y}$ Te $_{1 - x}$ Se $_{x}$ systems can indeed emerge in an environment where the spin correlation is not dominated by SAF.

Quantum confinement effects in Pb nanocrystals grown on InAs

Tianzhen Zhang, Sergio Vlaic, Stéphane Pons, Alexandre Assouline, Alexandre Zimmers, Dimitri Roditchev, Hervé Aubin, Guy Allan, Christophe Delerue, Christophe David, Guillemin Rodary, and Jean-Christophe Girard

Phys. Rev. B 97, 214514 (2018) - Published 19 June, 2018

In this article, the authors show that the two-dimensional electron gas at the surface of InAs provides a remarkable substrate for the growth of Pb nanocrystals. This is used to study the quantum confinement effects in such nanocrystals - since the Fermi wavelength of the two-dimensional electron gas is larger than the lateral size of the nanocrystal, the quantum constriction of the wavefunction at the interface leads to a weak coupling between the nanocrystal and the substrate and so preserves the quantum confinement effects within the nanocrystal. The researchers are able to observe the superconducting parity effect and the mapping of electronic wave functions via scanning tunneling spectroscopy.

Complete electrodynamics of a BCS superconductor with $μ eV$ energy scales: Microwave spectroscopy on titanium at mK temperatures

Markus Thiemann, Martin Dressel, and Marc Scheffler

Phys. Rev. B 97, 214516 (2018) - Published 20 June, 2018

Titanium is generally considered a conventional superconductor, but due to the experimental challenges that come with its low critical temperature $T$ $_{c}$ ≈ 0.5 K its superconducting properties have been only barely characterized so far. The authors apply a novel multimode microwave resonator technique to determine the complete optical response of superconducting titanium at extremely low energy scales (GHz frequencies and mK temperatures). The superconducting energy gap, superfluid density, and penetration depth are quantified, and it is demonstrated that titanium closely follows the electrodynamics predicted by BCS theory.
