There is considerable research interest in discovering new permanent magnetic materials that perform equally as champion neomagnets, with the minimal use of critical rare-earth elements. Recently ThMn_{12}-type (1:12) rare-earth iron (Ce-Fe) intermet

We study the modification of the electronic structure in the strong spin–orbit coupled Sr _2 IrO _4 by epitaxial strain using density-functional methods. Structural optimization shows that strain changes the internal structural parameters such as t

Iron-based hexaferrites are critical-element-free permanent magnet components of magnetic devices. Of particular interest is electron-doped M-type hexaferrite i.e., ${\mathrm{LaFe}}_{12}{\mathrm{O}}_{19}$ (LaM) in which extra electrons introduced by

Control of magnetism by an applied electric field is a desirable technique for the functionalization of magnetic materials. Motivated by recent experiments, we study the electric field control of the interfacial magnetism of ${\mathrm{CaRuO}}_{3}/{\m

We study the electronic and optical properties of NaOsO3 under epitaxial strain using first principles methods. Structural optimization shows important changes with strain in the structural parameters such as the Os O bond lengths and the octahedral

Distortion modes in halide perovskites: to twist or to stretch, a matter of tolerance and lone pairs
Using first-principles calculations, we show that $\mathrm{Cs}B{X}_{3}$ halides with $B=\text{Sn}$ or Pb undergo octahedral rotation distortions, while for $B=\text{Ge}$ and Si, they undergo a ferroelectric rhombohedral distortion accompanied by a rh

Deep defects in wide band gap semiconductors have emerged as leading qubit candidates for realizing quantum sensing and information applications. Due to the spatial localization of the defect states, these deep defects can be considered as artificial

Iridates are of considerable current interest because of the strong spin-orbit coupling that leads to a variety of new phenomena. Using density-functional studies, we predict the formation of a spin-orbital entangled two dimensional electron gas (2DE
