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…
Quantum Criticality and Incipient Phase Separation in the Thermodynamic Properties of the Hubbard Model
D. Galanakis, E. Khatami, K. Mikelsons +4
Transport measurements on the cuprates suggest the presence of a quantum critical point hiding underneath the superconducting dome near optimal hole doping. We provide numerical ev…
A dynamical mean-field approximation study of a tight-binding model for GaMnAs
A. -M. Nili, U. Yu, J. Moreno +2
The magneto-optical properties of the ferromagnetic semiconductor GaMnAs are studied within the dynamical mean-field approximation (DMFA). A material-specific multiba…
Kondo effect and absence of quantum interference effects in the charge transport of cobalt doped iron pyrite
S. Guo, D. P. Young, R. T. Macaluso +5
The Hall effect and resistivity of the carrier doped magnetic semiconductor FeCoS were measured for , temperatures between 0.05 and 300 K, and fiel…
Magnetic and thermodynamic properties of cobalt doped iron pyrite: Griffiths Phase in a magnetic semiconductor
S. Guo, D. P. Young, R. T. Macaluso +5
Doping of the band insulator FeS with Co on the Fe site introduces a small density of itinerant carriers and magnetic moments. The lattice constant, AC and DC magnetic suscepti…
The Role of Correlations in the Magnetic Moment of MnSi
Robert D. Collyer, Dana A. Browne
We explored the anomalously low moment in MnSi found by experiment (~0.4 /Mn) vs the moment predicted by density functional theory (~1.0 /Mn). With the…
