Improved Electrical Conductivity of Copper and Nitrogen Functionalized Carbon Nanotubes
Mina Yoon, German D. Samolyuk, Kai Li +2
In this work, we investigate the electrical conductivity of carbon nanotubes (CNTs), with a particular focus on the effects of doping. Using a first-principles approach, we study t…
Intricate magnetic landscape in antiferromagnetic kagome metal TbTiBi and interplay with LnTiBi (Ln: Tb-Lu) shurikagome metals
Brenden R. Ortiz, Heda Zhang, Karolina Gornicka +8
Here we present the discovery and characterization of the kagome metal TbTiBi in tandem with a new series of compounds, the LnTiBi (Ln: Tb-Lu) shurikago…
Evolution of highly anisotropic magnetism in the titanium-based kagome metals LnTiBi (Ln: La...Gd, Eu, Yb)
Brenden R. Ortiz, Hu Miao, David S. Parker +9
Here we present the family of titanium-based kagome metals of the form LnTiBi (Ln: La...Gd, Eu, Yb). Single crystal growth methods are presented alongs…
Extreme Fermi surface smearing in a maximally disordered concentrated solid solution
Hannah C. Robarts, Thomas E. Millichamp, Daniel A. Lagos +13
We show that the Fermi surface can survive the presence of extreme compositional disorder in the equiatomic alloy NiFeCoCr. Our high-resolution…
Unfolding the complexity of quasi-particle physics in disordered materials
Sai Mu, Raina Olsen, B. Dutta +9
The concept of quasi-particles forms the theoretical basis of our microscopic understanding of emergent phenomena associated with quantum mechanical many-body interactions. However…
Uncovering electron scattering mechanisms in NiFeCoCrMn derived concentrated solid solution and high entropy alloys
Sai Mu, G. D. Samolyuk, S. Wimmer +5
Whilst it has long been known that disorder profoundly affects transport properties, recent measurements on a series of solid solution 3d-transition metal alloys reveal two orders…
Quantum oscillations of nitrogen atoms in uranium nitride
A. A. Aczel, G. E. Granroth, G. J. MacDougall +5
The vibrational excitations of crystalline solids corresponding to acoustic or optic one phonon modes appear as sharp features in measurements such as neutron spectroscopy. In cont…
Magnetic Field Effects on Transport Properties of PtSn4
Eundeok Mun, Hyunjin Ko, Gordon J. Miller +3
The anisotropic physical properties of single crystals of orthorhombic PtSn4 are reported for magnetic fields up to 140 kOe, applied parallel and perpendicular to the crystallograp…
The influence of transition metal solutes on dislocation core structure and values of Peierls stress and barrier in tungsten
G. D. Samolyuk, Y. N. Osetsky, R. E. Stoller
Several transition metals were examined to evaluate their potential for improving the ductility of tungsten. The dislocation core structure and Peierls stress and barrier of $1/2<1…
Thermal expansion and magnetostriction of pure and doped RAgSb2 (R = Y, Sm, La) single crystals
S L Bud'ko, S A Law, P C Canfield +3
Data on temperature-dependent, anisotropic thermal expansion in pure and doped RAgSb2 (R = Y, Sm, La) single crystals are presented. Using the Ehrenfest relation and heat capacity…

We present anisotropic, zero applied magnetic field, temperature dependent resistivity measurements on hexagonal, non-magnetic, YPtIn and LuAgGe single crystals. For these material…
Role of Disorder in Mn:GaAs, Cr:GaAs, and Cr:GaN
J. L. Xu, M. van Schilfgaarde, G. D. Samolyuk
We present calculations of magnetic exchange interactions and critical temperature T_c in Mn:GaAs, Cr:GaAs and Cr:GaN. The local spin density approximation is combined with a linea…
