Emergent Magnetism, Heavy Electrons, and Pressure-Induced Reentrant Superconductivity in the Iron Substituted 4d Transition-Metal Sulfides. [PDF]
Adv Sci (Weinh)This work illustrates that magnetic Fe substitution enables systematic modulation of physical properties of the putative unconventional superconductor Rh17S15. Iron doping uncovers delicate competition between weak ferromagnetism, spin‐glass states, heavy‐fermion signatures, and superconductivity.

Pyrochlore from the Sokli carbonatite complex, Northern Finland [PDF]
Bulletin of the Geological Society of Finland, 1979 Pyrochlore from the Sokli carbonatite complex has been studied in four phoscorite and two regolith samples. The crystal forms of the euhedral pyrochlores are either an octahedron or a combination of an octahedron and a cube.

Synthesis and physical properties of pyrochlore cobalt oxides Bi1.56-xCaxSb1.48Co0.96O7-δ [PDF]
Cerâmica, 2023 A new solid solution Bi1.56-xCaxSb1.48Co0.96O7-δ (0≤x≤0.3) with a pyrochlore-like structure (A2B2O7) was synthesized in air by chemical solid-state reaction. The solution crystallized in the cubic system with the Fd-3m space group.

The XPS study of pyrochlore matrixes for the radioactive waste disposal [PDF]
Nuclear Technology and Radiation Protection, 2010 Two pyrochlore ceramic samples were studied in this work. The X-ray diffraction and the scanning electron microscopy showed that the ceramics with the calculated composition CaThSn2O7 was formed by the dominating pyrochlore phase with the traces of ...
