Cu3TeO6, a three-dimensional antiferromagnet forming a unique spin-web lattice of spin-1/2 Cu2+ ions below the Néel temperature TN ≈ 62 K, has recently been found to exhibit topological Dirac or nodal magnon dispersion. In this study, we report th

In most of the spin-induced multiferroics, the ferroelectricity is caused by inversion symmetry breaking by complex spin structures of the transition-metal ions. Here, we report the importance of interplay of 4f-3d magnetic interactions in inducing f

The bimetallic alloys often outperform their single-component counterparts due to synergistic effects. Being widely known, the Au–Pd alloy is a promising candidate for the novel heterogeneous nanocatalysts. Rational design of such systems requires

Density functional theory (DFT) calculations are performed to predict the structural, electronic and magnetic properties of electrically neutral or charged few-atomic-layer (AL) oxides whose parent systems are based on polar perovskite $KTaO_{3}$. Th

Thin films of sodium niobate (NaNbO3) on a MgO(001) substrate with a predeposited SrRuO3 layer were obtained for the first time by the method of RF cathode sputtering in an oxygen atmosphere. X‑ray diffraction data showed the obtained films to be s

The magnetic ground state of $\mathrm{Co}{\mathrm{Al}}_{2}{\mathrm{O}}_{4}$ has been a controversial issue because the ratio of nearest- (${J}_{1}$) to next-nearest-neighbor (${J}_{2}$) exchange interactions in the diamond lattice is close to the bou

The oxide interface has been studied extensively in the past decades and exhibits different physical properties from the constituent bulks. Using first-principles electronic structure calculations, we investigated the interface of CdTiO3/BaTiO3 (CTO/
