English terminology usually distinguishes between sorting and ordering. Sorting is primarily a service for users to facilitate their access to information by presenting it in a structured and predictable way, e. g. by subdividing the information by subject matter (by having several registers to a book, for instance), having multiple indices in a library etc. Ordering –– the arrangement of infor...

The ordered tetragonal intermetallic Cr$_2$Al forms the same structure type as Mn$_2$Au, and latter has been heavily investigated for its potential in antiferromagnetic spintronics due to degenerate in-plane N\'{e}el vector. We present single crystal flux growth of orientation-dependent magnetic properties. Powder neutron diffraction first-principles simulations reveal that ordering is likely t...

This work is based on the idea that extension of physical and mathematical theories to include the amount of space, time, momentum, and energy resources required to determine properties of systems may influence what is true in physics and mathematics at a foundational level. Background material, on the dependence of region or system sizes on both the resources required to study the regions or s...

The multi-instability of the electronic structure of (EDO-TTF)2PF6, where EDO-TTF means ethylene-dioxytetrathiafulvalene, is reviewed. This complex showed the metal-insulator transition at 280 K associated with distinct molecular deformations. The mechanism is interpreted as the cooperation of Peierls transition, charge ordering, and the order-disorder transition of the countercomponent. The ch...

In situ synchrotron diffraction measurements and subsequent Rietveld refinements are used to show that the high energy density cathode material LiCoPO4 (space group Pnma) undergoes two distinct two-phase reactions upon charge and discharge, both occurring via an intermediate Li2/3(Co2+)2/3(Co3+)1/3PO4 phase. Two resonances are observed for Li2/3CoPO4 with intensity ratios of 2:1 and 1:1 in the ...
