Abstract null null The properties of Pt-based materials can be intriguing due to the importance of spin-orbit coupling for Pt. Herein, we report four new phases with formulas M3Pt23Ge11 (M ​= ​Ca, Sr, Ba and Eu), which adopt the same structure type as Ce3Pt23Si11. Magnetic susceptibility measurements indicate that none of the phases is superconducting above 1.8 ​K, while for Eu3Pt23Ge11 ferromagnetic ordering is observed at ~ 3 ​K. The low Curie temperature for that material compared to that of ...

Zeolites are so well known in real world applications and after decades of scientific study that they hardly need any intro-duction: their importance in chemistry cannot be overemphasized. Here we add to the remarkable properties that they dis-play by reporting our discovery that the simplest zeolite, sodalite, when doped with Cr3+ in the \b{eta}-cage, is a frustrated magnet. Soft X-ray absorption spectroscopy and magnetic measurements reveal that the Cr present is Cr(III). Cr(III), with its iso...

We successfully dope the magnetically silent double perovskite semiconductor Sr2GaSbO6 to induce ferromagnetism and tune its band gap, with Ga3+ partially substituted by the magnetic trivalent cation Mn3+, in a rigid cation ordering with Sb5+. Our new ferromagnetic semiconducting Sr2Ga1-xMnxSbO6 double perovskite, which crystallizes in tetragonal symmetry (space group I4/m) and has tunable ferromagnetic ordering temperature and band gap, suggests that magnetic ion doping of double perovskites is...

The Kitaev model predicts that quantum spin liquids (QSLs) will form at low temperatures under certain special conditions, and materials hosting the QSL state are frequently sought. The layered honeycomb lattice material {\alpha}-RuCl3 has emerged as a prime candidate for displaying the Kitaev QSL state. Here we describe a new polymorph of RuI3 with a layered honeycomb lattice structure, synthesized at moderately high pressures and stable under ambient conditions. Preliminary characterization re...

We describe the crystal structure and elementary magnetic properties of a previously unreported ternary intermetallic compound, Cr4PtGa17, which crystallizes in a rhombohedral unit cell in the noncentrosymmetric space group R3m. The crystal structure is closely related to those of XYZ half-Heusler compounds, where X, Y, and Z are reported to be single elements only, occupying three different face-centered-cubic sublattices. The new material, Cr4PtGa17, can be most straightforwardly illustrated b...

We present the structural and initial magnetic characterization of the previously unreported materials NdPd5Ge3 and NdPd5Ge3. These materials, with 1-dimensional Nd chains, crystallize in the orthorhombic YNi5Si3-type structure in space group Pnma. Magnetic ordering is observed for both compounds at ~ 2.2 K for NdPd5Ge3 and ~ 3.0 K for NdPt5Ge3. A magnetic-field-induced transition is clearly observed for NdPd5Ge3 below 2K, at an applied magnetic field of around 1.6 Tesla. The heat capacity data ...

The crystal structure is closely related to those of XYZ half-Heusler compounds, where X, Y and Z were reported to be single elements only, most straightforwardly illustrated by writing the formula as (PtGa2)(Cr4Ga14)Ga (X=PtGa2, Y = Cr4Ga14, Z = Ga). The magnetic Cr occ...

These materials, with 1-dimensional Nd chains, crystallize in the orthorhombic YNi5Si3-type structure in space group Pnma. Magnetic ordering is observed for both compounds - at ~ 2.2 K for NdPd5Ge3 and ~ 3.0 K for NdPt5Ge3. A metamagnetic transition is clearly observed for NdPd5Ge3 below 2K, at an applied magnetic field of around 3 Tesla. The heat capacity data reveals th...

Transition metal stannides are usually semiconductors with a narrow band gap. We report experimental investigation on metallic Ir3Sn7-xMnx(x= 0 and 0.56). Single crystal x-ray diffraction refinement indicates that Ir3Sn7-xMnxcrystals form a cubic structure (space groupIm-3m) with the lattice parametera= 9.362(4) A forx= 0 and 9.328(6) A forx= 0.56. The electrical resistivity shows metallic behavior between 2 K and 300 K withT2dependence atT< 30 K forx= 0, reflecting the Fermi-liquid ground state...
