Structural Stability of Pyrochlore Manganate In2Mn2O7 Under High Pressure

Frontiers in Physics, 2021
The pyrochlore manganate In2Mn2O7 is a very promising ferromagnetic semiconductor material, which has a good application prospect in spin transport due to its very low electron effective mass, high Curie temperature, and structural stability.

3d-electron Heisenberg pyrochlore Mn2Sb2O7 [PDF]

, 2018
In frustrated magnetic systems, geometric constraints or the competition among interactions introduce extremely high degeneracy and prevent the system from readily selecting a low-temperature ground state. The most frustrated known spin arrangement is on

NEW DATA ON PYROCHLORE OF ALKALI PEGMATITES AND ORE ZONES OF THE VISHNEVYE MOUNTAINS (SOUTHERN URALS) [PDF]

Минералогия, 2018
The minerals of the pyrochlore group are abundant in rocks of the Vishnevogorsk alkaline complex – miaskites, mica rocks, carbonatites, and their pegmatites. Several generations of pyrochlore can be found in complex pegmatite bodies.

XPS and NEXAFS Studies of Zn-Doped Bismuth Iron Tantalate Pyrochlore

Inorganics, 2023
The effect of Zn-doping on the phase composition and optical properties of the Bi2ZnxFe1-xTa2O9.5-Δ (x = 0.3, 0.5, 0.7) was studied. XRD data showed that the samples crystallize in the structural type of pyrochlore (sp. gr.Fd-3m). For all the samples, an
