Tricritical wetting in the two-dimensional Ising magnet due to the presence of localized non-magnetic impurities
(IOP Publishing, 2016-02)
Fixed vacancies (non-magnetic impurities) are placed along the centre of Ising strips in order to study the wetting behaviour in this confined system, by means of numerical simulations analysed with the aid of finite size ...

Theory of non-steady state electrical characteristics of metal-insulator-metal structures with schottky barriers and exponentially distributed impurity states
(1996-12-01)
We discuss non-steady state electrical characteristics of a metal-insulator-metal structure. We consider an exponential distribution (in energy) of impurity states in addition to impurity states at a single energy level ...
Effect of impurities and sintering temperature on properties of MgO-CaZrO3 ceramic
(Elsevier, 2013-10)
CaZrO3 -MgO ceramics are useful as refractories in kilns for the cement production. One method of manufacture of such ceramics is by sintering from m-ZrO2 and dolomite MgCa(CO3 )2 mixtures. In this work electrofused m-ZrO2 ...
Spin response of impurities in a quantum corral
(World Scientific, 2014-04)
In this work we investigate the dependence of spin observables, like the total spin alignment and the spin squeezing factor, for electrons confined inside an elliptic quantum corral and interacting with a pair of impurities ...

Interaction of hydrogen in carbon matrix with impurities of nickel. Effects of spin fluctuation
(Pergamon-Elsevier Science Ltd, 2014-05)
This work aims to define general criteria to allow theoretical and experimental design of new materials with high hydrogen content, with a view to their potential application as moderators in reactors at high temperatures ...
