Systematic Investigations of the Solid Solution Zr(V1-xAlx)2 Adopting the Laves Phase Structures.

Laves phases are an interesting field of research when it comes to structural chemistry and physical properties. Investigations of the ternary system Zr-V-Al showed, in contrast to the system Hf-V-Al, that no superstructures can be observed within the solid solution Zr(V1-xAlx)2. High values of x form aluminum rich phases that adopt the hexagonal MgZn2 type structure while low values of x lead to vanadium rich phases that adopt the cubic MgCu2 type.

Synthesis, magnetic and NMR spectroscopic properties of the MAlPt series (M = Ca, Y, La-Nd, Sm-Er).

Following recent investigation in the ternary system Sr-Al-Pt led to the discovery of SrAlPt which crystallizes in the orthorhombic YNiSi type () structure. Interestingly, only two more aluminum representatives, CeAlPt and EuAlPt, have been reported to adopt this structure type. Therefore, we decided to investigate the existence range of compounds adopting the YNiSi type structure.

Computational and Experimental Investigations of Osmium-Rich Borides HfMOsB (M = Mn, Fe, Co): From Spin Glass to Room-Temperature Magnetic Behaviors.

The metal borides, HfMOsB (M = Mn, Fe, Co), which are the first Os-rich quaternary variants of the prolific TiCoB structure type, were investigated computationally and experimentally. In their crystal structures, osmium builds a network of prisms, in which the other elements are located. The magnetic M elements are found in face-connected Os square prisms leading to M-chains with intra- and interchain distances of about 3.

Enhancing Intrinsic Magnetic Hardness by Modulating Antagonistic Interactions in the Rare-Earth-Free Magnetic Solid Solution Hf Fe Ru Ir B.

The quinary members in the solid solution Hf Fe Ru Ir B (x=1-4, VE=63-66) have been investigated experimentally and computationally. They were synthesized via arc-melting and analyzed by EDX and X-ray diffraction. Density functional theory (DFT) calculations predicted a preference for magnetic ordering in all members, but with a strong competition between ferro- and antiferromagnetism arising from interchain Fe-Fe interactions.
