Synthesis and structural study of the partially disordered complex hexagonal phase δ-MnZn.

A detailed structural analysis of the Zn-rich δ-MnZn phase using single-crystal X-ray diffraction is presented. The δ phase has been synthesized by the high-temperature synthetic route. The structure crystallizes in space group P6/mmc (Pearson symbol hP556) with unit-cell parameters: a = b = 12.

Understanding of magnetic behavior of the pseudo-binary CoNiZn: in the light of crystal and electronic structures.

A high-temperature synthetic approach is used to prepare a series of pseudo-binary phases-CoNiZn. In the structures of CoNiZn, the statistical distribution between Co and Ni that is suggested by compositional analysis is confirmed by combined refinements of X-ray and neutron powder diffraction (NPD) experimental data. The aforementioned phases adopt a body-centered cubic lattice with a noncentrosymmetric space group 4̄3 (217).

Double Helix of Icosahedra Structure and Spin Glass Magnetism of the δ-CoZnMn ( = 0.4-3.5) Pseudo-Binary Alloys.

We have synthesized δ-CoZnMn ( = 0.4-3.5) pseudo-binary alloys of 10 different compositions by a high-temperature solid-state synthetic route, determined their crystal structures and the Mn substitution pattern, and estimated the existence range of the δ-phase.
