Journal ArticleDOI
Influence of chemical disorder on energy dissipation and defect evolution in concentrated solid solution alloys.
Yanwen Zhang,G. Malcolm Stocks,Ke Jin,Ke Jin,Chenyang Lu,Hongbin Bei,Brian C. Sales,Lumin Wang,Laurent Karim Béland,Roger E. Stoller,German D. Samolyuk,M. Caro,Alfredo Caro,William J. Weber,William J. Weber +14 more
TL;DR: It is reported that chemical disorder, with an increasing number of principal elements and/or altered concentrations of specific elements, in single-phase concentrated solid solution alloys can lead to substantial reduction in electron mean free path and orders of magnitude decrease in electrical and thermal conductivity.
Journal ArticleDOI
Pressure-induced volume-collapsed tetragonal phase of CaFe2As2 as seen via neutron scattering
A. Kreyssig,Mark Green,Y. Lee,German D. Samolyuk,Paweł Zajdel,Jeffrey W. Lynn,S.L. Bud'ko,M. S. Torikachvili,N. Ni,Shibabrata Nandi,J. B. Leão,S. J. Poulton,Dimitri N. Argyriou,B. N. Harmon,Robert J. McQueeney,P. C. Canfield,Alan I. Goldman +16 more
TL;DR: In this article, it was shown that CaFe2As2 undergoes a pressure-induced transition to a nonmagnetic volume "collapsed" tetragonal phase, which becomes superconducting at lower temperature.
Journal ArticleDOI
Tailoring the physical properties of Ni-based single-phase equiatomic alloys by modifying the chemical complexity
Ke Jin,Brian C. Sales,G. M. Stocks,German D. Samolyuk,Markus Daene,William J. Weber,William J. Weber,Yanwen Zhang,Yanwen Zhang,Hongbin Bei +9 more
TL;DR: A family of (eight) Ni-based, face-center-cubic (FCC), equiatomic alloys, extending from elemental Ni to quinary high entropy alloys has been synthesized, and their electrical, thermal, and magnetic properties are systematically investigated.
Journal ArticleDOI
Uncovering electron scattering mechanisms in NiFeCoCrMn derived concentrated solid solution and high entropy alloys
Sai Mu,German D. Samolyuk,Sebastian Wimmer,M. C. Troparevsky,Suffian N. Khan,Sergiy Mankovsky,Hubert Ebert,G. M. Stocks +7 more
TL;DR: In this paper, the authors used ab initio methods to investigate electron scattering mechanisms behind differences in residual resistivity of the Cantor-Wu family of face-centered cubic disordered alloys.
Journal ArticleDOI
K-doping dependence of the Fermi surface of the iron-arsenic Ba1-xKxFe2As2 superconductor using angle-resolved photoemission spectroscopy.

TL;DR: This study indicates that the Fermi surface of the undoped, parent compound BaFe_( 2)As_(2) consists of hole pocket(s) at Gamma (0,0) and larger electron pocket(S) at X (1,0), in general agreement with full-potential linearized plane wave calculations.
