Self-Consistent Supercell Band-Structure Calculations for the Investigation of the Electric Field Gradient at Impurity Sites in Cd Metal
The electric field gradient (EFG) at the nuclei of the 5 sp impurities In, Sn, Sb, I and Xe in Cd metal is investigated on the basis of supercell band structure calculations of C d15M (M = I n , . . . , Xe). The theoretical results show the same trend as the experimental findings. The differences in the EFG for different impurities are related to the charge distribution and partial densities of...
متن کاملConvergence of electric field and electric field gradient versus atomic basis sets in all-siliceous and Mg substituted phillipsites
Electrostatic potential (EP), electric field (EF), and electric field gradient (EFG) values are calculated in periodic models of magnesium substituted phillipsite (MgPHI) zeolite forms using periodic DFT (PDFT) hybrid B3LYP level with fourteen different basis sets. Relative root mean square differences between the EP, EF, or EFG values estimated between different basis sets are evaluated in sev...
متن کاملSpin-Orbit Electric Field Gradient in Cubic Ferromagnets: Strong Magnetization-Direction Dependence of the Field Gradient Distribution
The ISOLDE Collaboration CERN, CH-1211 Geneva 23, Switzerland (Received 19 March 1998; revised manuscript received 19 October 1998) The electric quadrupole interaction of 191Pt (I 3y2; T1y2 2.9 d) in an Fe single crystal was measured for magnetization M parallel to the crystallographic [100], [110], and [111] axes. For M k f111g and [110] the distribution of the electric field gradient (EFG...
متن کاملElectric Field Gradient in Aluminium due to Vacancy and Muon *
The electric field gradients (EFG) in aluminium due to a monovacancy and the interstitial muon are evaluated. The valence effect EFG q is calculated using perturbed electron density ön(r) values obtained from density functional theory in an analytic expression which is valid at all distances from the impurity. The size effect E F G q is evaluated using a new oscillatory form for the near neighb...
متن کاملElectric Field Gradient at Nb Site in the Intermetallic Compounds
The electric field gradient (efg) at the Nb site in the intermetallic compounds Nb3X (X = Al, In, Si, Ge, Sn) was measured by the Perturbed Angular Correlation (PAC) method using the wellknown gamma-gamma cascade of 133 482 keV inTa from the decay of Hf, substituting approximately 0.1 atom percent of Nb. The PAC results show that Vzz drops by nearly 40% when X changes from Al to In, and by abou...
