Altering the magnetic ordering of FeGa via thermal annealing and hydrostatic pressure
Brandon Wilfong, Vaibhav Sharma, Jared Naphy +5
The effects of post-synthesis annealing temperature on arc-melted samples of FeGa has been studied to investigate changes in crystallographic and magnetic properties in…
Anomalous and Anisotropic Nonlinear Susceptibility in the Proximate Kitaev Magnet -RuCl
Ludwig Holleis, Joseph Prestigiacomo, Zhijie Fan +5
The leading order nonlinear (NL) susceptibility, , in a paramagnet is negative and diverges as . This divergence is destroyed when spins correlate and the NL…
Superconducting properties of tin-based ENZ and hyperbolic metamaterials
V. N. Smolyaninova, W. Korzi, W. Zimmerman +10
Recent experiments have demonstrated that the superconducting critical temperature may be improved in various metamaterial superconductor geometries. Here, we present the results o…
Observation of plasmon-phonons in a metamaterial superconductor using inelastic neutron scattering
Vera N. Smolyaninova, Jeffrey W. Lynn, Nicholas P. Butch +4
Metamaterial approach is capable of drastically increasing the critical temperature, Tc, of composite metal-dielectric superconductors. Tripling of Tc was observed in bulk Al-Al2O3…
Enhanced superconductivity in aluminum-based hyperbolic metamaterials
V. N. Smolyaninova, C. Jensen, W. Zimmerman +6
One of the most important goals of condensed matter physics is materials by design, i.e. the ability to reliably predict and design materials with a set of desired properties. A st…
Using core-shell metamaterial engineering to triple the critical temperature of a superconductor
Vera N. Smolyaninova, Kathryn Zander, Thomas Gresock +4
Recent experiments have shown the viability of the metamaterial approach to dielectric response engineering for moderately enhancing the transition temperature, Tc, of a supercondu…
Effects of pressure on the magnetostructural and magnetocaloric properties of isostructurally alloyed (MnNiSi)1-x(FeCoGe)x
Tapas Samanta, Daniel L. Lepkowski, Ahmad Us Saleheen +11
The isostructural alloying of two compounds with extremely different magnetic and thermo-structural properties has resulted in a new system, (MnNiSi)1-x(FeCoGe)x, that exhibits ext…
Magnetic, thermodynamic, and electrical transport properties of the noncentrosymmetric B20 germanides MnGe and CoGe
J. F. DiTusa, S. B. Zhang, K. Yamaura +9
We present magnetization, specific heat, resistivity, and Hall effect measurements on the cubic B20 phase of MnGe and CoGe and compare to measurements of isostructural FeGe and ele…
Pressure-induced giant enhancement of magnetocaloric effects in MnNiSi-based systems
Tapas Samanta, Daniel L. Lepkowski, Ahmad Us Saleheen +11
A remarkable decrease of the structural transition temperature of MnNiSi from 1200 K to <300 K by chemically alloying it with MnFeGe results in a coupling of the magnetic and struc…
Ferromagnetic Quantum Critical Point in FeGa3 Tuned by Mixed-Valence Fe Dimers
N. Haldolaarachchige, J. Prestigiacomo, W. Adam Phelan +9
The magnetic, transport, and thermal properties of single crystals of the series Fe(Ga1-xGex)3 are reported. Pure FeGa3 is a nonmagnetic semiconductor, that when doped with small c…
Exchange Field-Mediated Magnetoresistance in the Correlated Insulator Phase of Be Films
T. J Liu, J. C. Prestigiacomo, Y. M. Xiong +1
We present a study of the proximity effect between a ferromagnet and a paramagnetic metal of varying disorder. Thin beryllium films are deposited onto a 5 nm-thick layer of the fer…
