The results of new magnetic dc and neutron diraction measurements of DyCoSi2 compound are presented. Below TN equal to 10.9 K the Dy moments form collinear G-type structure with the moment parallel to the c-axis. The value of Dy-moment equal to 5.5(2) µB are smaller than free Dy 3+ ion value (10.0 µB). These and the three-step magnetization process indicate the strong inuence of the crystal electric eld on the stability of the magnetic order. Increase of the values of the lattice parameters at 1.5 K in reference of these at 20 K indicate magnetostriction eect at low temperatures.

“…The main feature of La 12 Ga 3.26 Sb 24.02 structure is the presence of pseudo-trigonal fragments formed by lanthanum atoms around triangular GaSb 3 planar units (figure, top). This structural units are also an inherent feature of the structure of La 13 Ga 8 Sb 21 [1] and series of hexagonal structures R 6 Ni 2 Si 3 (R = La -S m, Gd) [2][3][4][5][6][7]. Trigonal-prismatic channels formed by La atoms are outlined by corrugated Sb nets interconnected by Ga atoms.…”

Source of materialThe synthesis was performed from pure elements: lanthanum (Ames, 99.995 wt %), gallium (Chempur, 99.999 wt %) and antimony (Chempur, 99.9999 wt %). Initially La and Ga were arcmelted in the atomic ratio 1:1. The mixture of LaGa precursor with excess of Sb (1:15) was put into glassy carbon crucible, sealed in tantalum container and enclosed in aquartz tube. The following thermal treatment was carried out: heating to 1000°C within 5h ,a nnealing at this temperature for 170 h, cooling to 500°Cwith the rate 4°C/h and subsequent annealing at this temperature for 35 days. The Sb excess was removed by sublimation at 500°Cunder vacuum.

Abstract:Intermetallic crystal structures offer an enormous structural diversity, with an endless array of structural motifs whose connection to stability and physical properties are often mysterious. Making sense of the often complex crystal structures that arise here, developing a clear structural description, and identifying connections to other phases can be laborious and require an encyclopedic knowledge of structure types. In this Article, we present PRINCEPS, an algorithm based on a new coordination environment projection scheme that facilitates the structural analysis and comparison of such crystal structures. We demonstrate the potential of this approach by applying it to the complex Ce-Ni-Si ternary system, whose 17 binary and 21 ternary phases would present a daunting challenge to one seeking to understand the system by manual inspection (but has nonetheless been well-described through the heroic efforts of previous researchers). With the help of PRINCEPS, most of the ternary phases in this system can be rationalized as intergrowths of simple structural fragments, and grouped into a handful of structural series (with some outliers). These results illustrate how the PRINCEPS approach can be used to organize a vast collection of crystal structures into structurally meaningful families, and guide the description of complex atomic arrangements.
