  • Author(s): Ravi Kumar, Soma Banik, Shashwati Sen, Shambhu Nath Jha, and Dibyendu Bhattacharyya Magnetic ion doping in topological insulators (TI's) has emerged to be important both from technological point of view and for experimental verification of exotic fundamental physical concepts. Magnetic ion doping not only opens up the energy gap in surface states of a TI but also changes its bulk b… [Phys. Rev. Materials 6, 114201] Published Mon...
  • Author(s): Moritz M. Hirschmann, Alexandra S. Gibbs, Fabio Orlandi, Dmitry Khalyavin, Pascal Manuel, Vahideh Abdolazimi, Alexander Yaresko, Jürgen Nuss, H. Takagi, Andreas P. Schnyder, and Andreas W. Rost The band topology of magnetic semimetals is of interest both from the fundamental science point of view and with respect to potential spintronics and memory applications. Unfortunately, only a handful of suitable topological semimetals with magnetic...
  • Author(s): Shuaishuai Yuan and Kirk H. Bevan The transition between delocalized and localized electronic configurations is a characteristic property of all small-polaron systems. In this study, we explore a doping approach by which the coexistence between delocalized and localized electronic states may be precisely tuned within extrinsic polar… [Phys. Rev. Materials 6, 114602] Published Mon Nov 28, 2022
  • Author(s): Manuel Brinker, Marc Thelen, Manfred May, Dagmar Rings, Tobias Krekeler, Pirmin Lakner, Thomas F. Keller, Florian Bertram, Norbert Huber, and Patrick Huber Macroscopic strain experiments have revealed that silicon crystals traversed by parallel, channel-like nanopores functionalized with the artificial muscle polymer polypyrrole (PPy) exhibit large and reversible electrochemomechanical actuation in aqueous electrolytes. On a macroscopic...
  • Author(s): Dingbin Huang, Deyuan Lyu, Xinjun Wang, Michael B. Katz, Delin Zhang, Jian-Ping Wang, Daniel B. Gopman, and Xiaojia Wang The moderate bulk perpendicular magnetic anisotropy (PMA, ${K}_{\mathrm{u}}≈\phantom{\rule{0.16em}{0ex}}1\phantom{\rule{0.16em}{0ex}}\mathrm{MJ}/{\mathrm{m}}^{3}$) and low Gilbert damping (α 0.01) make $L{1}_{0}$-FePd a promising candidate for energy-efficient and nonvolatile spintronic devices wit… [Phys. Rev...
  • Author(s): Rui Wang, Xiaoxiao Ma, Linfeng Zhang, Han Wang, David J. Srolovitz, Tongqi Wen, and Zhaoxuan Wu BCC transition metals (TMs) exhibit complex temperature and strain-rate dependent plastic deformation behavior controlled by individual crystal lattice defects. Classical empirical and semiempirical interatomic potentials have limited capability in modeling defect properties such as the screw disloc… [Phys. Rev. Materials 6, 113603] Published...
  • Author(s): Flynn Walsh, Robert O. Ritchie, and Mark Asta Contrary to prior calculations, the Ni-rich ordered structures of the Cr-Ni alloy system are found to be antiferromagnetic under semilocal density-functional theory. The optimization of local magnetic moments significantly increases the driving force for the formation of ${\mathrm{CrNi}}_{2}$, the o… [Phys. Rev. Materials 6, 113602] Published Tue Nov 22, 2022
