Quadruple perovskites are characterized by competing long-range spin interactions that result in complex magnetic structures. Here, the authors synthesize and characterize the magnetic behaviour of CaCo3Ti4O12, suggesting that the observed magnetic s

The development in materials science and pharmaceutics shows that there exist some key materials genomes, i.e., certain groups of atoms with specific constituents and structures, which govern the property of a series of materials based on them. To pi

Noncentrosymmetric hybrid framework (HF) materials are an important system in discovering new practical second-order nonlinear optical materials. We calculated the second harmonic generation (SHG) response of a noncentrosymmetric (NCS) organic–inor

Abstract Cu2O nanoparticles (NPs) enclosed with different crystal facets, namely, c‐Cu2O NPs with {100} facets, o‐Cu2O NPs with {111} facets, and t‐Cu2O NPs with both {111} and {100} facets, are prepared and their electrocatalytic properties fo

We determined the spin exchanges between the Cu2+ ions in the kagomé layers of volborthite, Cu3V2O7(OH)2·2H2O, by performing the energy-mapping analysis based on DFT+U calculations, to find that the kagomé layers of Cu2+ ions are hardly spin-frust

We examined the magnetic ground states, the preferred spin orientations and the spin exchanges of four layered phases MPS3 (M = Mn, Fe, Co, Ni) by first principles density functional theory plus onsite repulsion (DFT + U) calculations. The magnetic g

The onsite repulsion, spin–orbit coupling and polarizability of elements and their ions play important roles in controlling the physical properties of molecules and condensed materials. In celebration of the 150th birthday of the periodic table thi
