  • Entropy-dominated stacking fault nucleation in compressed Cu thin films

    Author(s): Jacques G. Amar, Danny Perez, and Akemi McHan We study stacking fault (SF) formation in compressed Cu thin films using harmonic transition state theory (HTST), harmonic variational transition state theory (HVTST), and molecular dynamics (MD). Motivated by prior simulations showing extremely large transition rates, we quantify the temperature, s… [Phys. Rev. Materials 10, 023603] Published Mon Feb 23, 2026

  • Towards fatigue failure prediction via acoustic emission analysis

    Author(s): Shimon Bettan, Eilon Faran, Ronen Talmon, and Doron Shilo This study presents and tests several approaches for predicting fatigue failure in metals using acoustic emission data analysis. We demonstrate that conventional single-valued AE features (event rate, amplitude, power-law exponents) fail to correlate with fatigue damage progression in selective lase… [Phys. Rev.

  • Temperature dependence of bulk and interface contributions to the magnetic damping of Permalloy thin films

    Author(s): Verena Ney, Kilian Lenz, Fabian Ganss, René Hübner, Jürgen Lindner, and Andreas Ney The magnetic damping of ${\mathrm{Ni}}_{80}{\mathrm{Fe}}_{20}$ [Permalloy (Py)] thin films is studied via temperature- and frequency-dependent ferromagnetic resonance (FMR) as a function of the Py layer thickness for two different thickness series, Al/Py/sapphire and Al/Py/Al/sapphire, respectively.… [Phys.

  • Ab initio study of point defects in disordered solid electrolytes ${\mathrm{Li}}_{3}A{\mathrm{Cl}}_{6} (A=\mathrm{Y},\mathrm{Er},\mathrm{In})$ ...

    Author(s): Tanmoy Paul Here, first-principles calculations help us understand solid-state electrolytes within the framework of point defects, considering Schottky, cation, and anion Frenkel defects, Li as interstitial defects, Li deficiencies as vacancies, and isovalent/anisovalent substitutional defects by anions. The de… [Phys. Rev. Materials 10, 025404] Published Mon Feb 23, 2026

  • Thermally activated epitaxy of NbO

    Author(s): Sandra Glotzer, Jeong Rae Kim, and Joseph Falson Refractory metal compounds are difficult to synthesize due to the extreme thermodynamic windows required, and therefore deconvoluting intrinsic properties from extrinsic effects can be challenging. This work dives into the synthesis and electronic properties of thin films of the refractory metal oxide NbO utilizing ultrahigh growth temperatures. The highlight is the ability to access...

  • Dielectric function and electronic structure of nondegenerate rocksalt ScN: Spectroscopic ellipsometry and $\mathit{GW}$ calculations

    Author(s): Jona Grümbel, Rüdiger Goldhahn, Martin Feneberg, Yuichi Oshima, Hazem Abu-Farsakh, and Abdallah Qteish In this work, we determine the dielectric function of ScN in a spectral range from 0.9 to $6.4\phantom{\rule{0.28em}{0ex}}\mathrm{eV}$ by spectroscopic ellipsometry from nondegenerate doped, bulk-like samples. Several models are applied to the obtained dielectric functions yielding the main critical… [Phys. Rev. Materials 10, 024607...

  • Magnetic structure evolution and magnetoelastic coupling across the spin reorientation transition in ${\mathrm{TmCrO}}_{3}$

    Author(s): Vishesh Sharma, Gaurav Gautam, Poonam Yadav, Chin-Wei Wang, Kaya Wei, N. P. Lalla, Theo Siegrist, and Shivani Sharma We present a comprehensive study of the magnetic structure evolution, employing bulk magnetization and neutron powder diffraction (NPD) measurements down to 3.5 K, across the spin reorientation transition in orthorhombic (Pnma) ${\mathrm{TmCrO}}_{3}$. Magnetic susceptibility reveals canted antiferro… [Phys. Rev. Materials...
