    Effects of local geometry distortion at the Al/Al2Cu interfaces on solute segregation and the similar Si concentration across the semicoherent interface. The lattice mismatch effect on the solute segregation energy is investigated as well. At low lattice mismatch (%), the segregation energies of Si and Mg are almost compatible Author: Xuemei Zhang, Yongsheng Zhang. We present a systematic study of the local distortions produced upon doping metal ions to lithium niobate (LiNbO 3, LN) single healthtechdays.com impurity bond length can be predicted by a radial force constant model, when the dopant ions substitute for Li + or Nb 5+ ions in the LN crystallographic frame.

Feb 01,  · The local lattice distortion at the trigonal Cr 3+ center in BiI3 is theoretically studied by the perturbation formulas of the EPR parameters for a 3d 3 ion in trigonal symmetry, based on the cluster approach. In these formulas the contributions from the s-orbitals of the ligands, which were often ignored, are taken into healthtechdays.com: Shao-Yi Wu, Xiu-Ying Gao, Hui-Ning Dong.

    Apr 21,  · In fact, the correlated local lattice distortion clearly shows up in the infrared phonon spectra in accord with the spin-state crossover, although the average lattice structure appears to be undistorted from that of the ground state. This is another example of thermally induced dynamical JT effect due to short-range orbital order, in addition Cited by: Rice University physicists used simulations and neutron scattering experiments to show the presence of tiny lattice distortions near the optimal superconductivity of an iron pnictide compound.

Kurchatov Institute of Atomic Energy, MoscowUSSR Received 5 December ; accepted for publication 20 December Communicated Cited by: Based on the absence of magnetic effects in this temperature range for the superconducting sample, we attribute the observed lattice anomalies to the formation of local lattice distortions that, being screened by the carriers, can only acquire long-range coherence Cited by: 7.

Abstract. A theoretical overview of the cooperative Jahn-Teller effect in the insulating phase is given. We obtain an effective Hamiltonian of an interaction between the orbital states of the Jahn-Teller ions through a canonical transformation, which associates each electronic state with a local lattice distortion, and by use of the mean field healthtechdays.com by: Nov 22,  · Thus, the Yb 2+ ions with large atomic size should squeeze into a rigid crystal lattice below T v, and large lattice distortions are expected around the Yb 2+ ions.

the lattice thermal resistance is governed by local distortions of the MnO 6 octahedra that are substantially altered by the phase transitions and in applied magnetic fields.

These local lattice distortions may be responsible for the low temperature magnetic crossover. We also discuss prospects for negative thermal expansion and show that there is not a straightforward low pressure pathway between the pink α and blue β ambient pressure phases of Co[N(CN)2]healthtechdays.com by: 7.

In this article, phase separation and lattice distortions are examined on the most characteristic family of high temperature superconductors, the cuprates. The effect of doping or atomic substitutions on cuprates is examined concerning the induced phase separation and hydrostatic pressure for activating small local lattice distortions at the Author: Efthymios Liarokapis.

In physics, a lattice model is a physical model that is defined on a lattice, as opposed to the continuum of space or spacetime. Lattice models originally occurred in the context of condensed matter physics, where the atoms of a crystal automatically form a lattice.

Lattice distortions constitute one of the main features characterizing high entropy alloys. Local lattice distortions have, however, only rarely been investigated in these multi-component alloys.
