On the one hand, the enhancement of the mechanical properties of doped specimens is mainly attributed to the growth twins and nanoprecipitates induced by doping the transition element. On the other hand, the weakened magnetic properties of the doped specimens ascribed to the accumulations consisting ...

Electronic structures and magnetic properties of LaAVMoO6 (A=Ca,Sr,Ba): Investigation of possible half-metallic antiferromagnets We have investigated electronic structures and magnetic properties of double perovskite LaAVMoO6 (A=Ca,Sr,Ba). The normal metallic and ferrimagnetic states... SP Min,BI...
There exist several reasons to pick out the physics of transition group metals as a separate branch of solid state physics. The first one is the variety of properties of transition metals (TM) and their compounds, which are not only much more complicated, but have some important peculiarities ...

What are three physical properties of elements? In order to know the physical properties of elements, a person can gather information through the five senses. Color, hardness, and density are some examples of physical properties.What are Elements? Elements are the most basic form of matter, and...
Secondly, we address the question regarding the influence of the polypeptide primary structure on silk material properties by analysing the experimental results in terms of the underlying fibroin amino acid sequences from the different species. Fourteen types of cocoon silks were investigated, ...
Silk has attracted widespread attention due to its superlative material properties and promising applications. However, the determinants behind the variations in material properties among different types of silk are not well understood. We analysed the p
Chromium Properties:Chromium has amelting pointof 1857+/-20°C, a boiling point of 2672°C, a specific gravity of 7.18 to 7.20 (20°C), with valences usually 2, 3, or 6. The metal is a lustrous steel-gray color which takes a high polish. It is hard and resistant to corrosion. ...
Some statistical properties of simple classically stochastic quantum systems Numerical studies are made of simple one- and two-dimensional quantum models which are stochastic in the classical limit. It is shown that the correlation ... DL Shepelyansky - 《Physica D Nonlinear Phenomena》 被引量: 20...
