(American Physical Society, 2004)The Hall effect has been studied in some Co-rich ferromagnetic metallic glasses which show resistivity (rho) minima at low temperatures. It is found that the extraordinary Hall constant (R-s) shows a corresponding minimum. ...
-
(American Physical Society, 2003)Using a rotating magnetic field, the Hall effect in three-dimensional amorphous GdxSi1-x has been measured in the critical regime of the metal-insulator transition for a constant total magnetic field. The Hall coefficient ...
-
(American Physical Society, 1993)The resistivity of codeposited amorphous Ti1-xAlx films has been measured from 1.5 to 300 K over the composition range 0.4 less-than-or-equal-to x less-than-or-equal-to 0.92, and the Hall coefficient has been measured at ...
-
(American Physical Society, 2006)We report on a comprehensive study of the ferromagnetic moment per Mn atom in (Ga,Mn)As ferromagnetic semiconductors. Theoretical discussion is based on microscopic calculations and on an effective model of Mn local moments ...
-
(American Physical Society, 2009)Starting with a microscopic model based on the Kohn-Luttinger Hamiltonian and kinetic p-d exchange combined with Boltzmann formula for conductivity we identify the scattering from magnetic Mn combined with the strong ...
-
(American Physical Society, 2007)A remarkable progress towards functional ferromagnetic semiconductor materials for spintronics has been achieved in p-type (Ga,Mn)As. Robust hole-mediated ferromagnetism has, however, been observed also in other III-V hosts ...
-
(American Physical Society, 2009)We present a procedure for finding the exact solution to the linear-response Boltzmann equation for two-dimensional anisotropic systems and demonstrate it on examples of noncrystalline anisotropic magnetoresistance in a ...
-
(American Physical Society, 2003)The Ginzburg-Landau coefficients and the jump of the specific heat are calculated for a disordered two-band superconductor. We start with the analysis of a more general case with arbitrary anisotropy. While the specific-heat ...
-
(American Physical Society, 2001)Magnetic and transport measurements indicate FeAl2 to be an ordered intermetallic spin glass, with canonical behavior including a susceptibility cusp at T-f = 35 K and frequency-dependent susceptibility below T-f. The ...
-
(American Physical Society, 2009)We present a study of transport in multiple-band noninteracting Fermi metallic systems based on the Keldysh formalism and the self-consistent T-matrix approximation (TMA) taking into account the effects of Berry curvature ...
-
(American Physical Society, 2004)We have performed detailed conductivity and tunneling measurements on the amorphous, magnetically doped material alpha-GdxSi1-x, which can be driven through the metal-insulator transition by the application of an external ...
