The layered lanthanum carbide halide superconductors La2C2(X,X')2 (X,X'= Cl, Br, I): neutron powder diffraction characterization and electronic properties
Article Abstract:
The neutron powder diffraction characterization technique is deemed effective in evaluating the phase purity of superconductors. Compared to conventional X-ray methods, neutron powder diffraction allows users to improve the accuracy of the positional parameters of carbon atoms. Actual neutron diffraction measurements revealed that superconductivity among lanthanum carbide superconductors takes effect at exactly 7 Kelvin, regardless of the way samples have been prepared. Results also showed a marked difference in the transition temperatures of 1s type and 3s type lanthanum carbide samples.

Calculation of magnetic properties and analysis of valence electronic structures of LaT13-xAlx (T = Fe, Co) compounds
Article Abstract:
The magnetic properties of LaT(sub 13-x)Al(sub x) were measured using the empirical electron theory. The hybridization in various atomic states were examined. A conformity between the experimental findings and calculated data on the magnetic properties of the compounds were observed. Meanwhile, the valence electronic structures revealed a correlation between the electronic structures and magnetic properties of the samples. The electronic properties of the cobalt atoms and the magnetic properties of the whole compound were influenced by the aluminum content of LaCo(Sub 13-x)Al(sub x).

Investigation of the influence of intercalation on the magnetic properties of FexCd1-xPS3 layered compounds
Article Abstract:
A study was conducted to determine the effects of intercalation on the magnetic properties of FexCd1-xPS3 layered compounds. Findings indicate that Fe(super 2+) ions' strong in-plane magnetic interactions prevents them from randomly scattering on the metallic sites during intercalation, However, it was observed that intercalation distorts the coordination sphere of Fe(Super 2), and thus, affecting its magnetic coupling.
