The detailed structural, magnetic, and cryogenic magneto-caloric properties of chromium-substituted gadolinium iron garnet (Gd 3 Fe 5- x Cr O 12 ) nanocrystalline powders were studied using the facile autocombustion method a calcination temperature 1100 °C. X-ray diffraction pattern showed that all samples single-phase with cubic Ia3 d symmetry. field-dependent magnetization data Gd revealed fe...

Novel physical phenomena arising from the complex interplay between spin, charge, orbital, and lattice orders can emerge in perovskite-type oxide heterostructures. Here, we investigate electronic structures on interface of YBa2Cu3O7/LaAlO3 heterostructure prepared by pulsed laser deposition with combination spherical aberration-corrected scanning transmission electron microscopy density functio...

Abstract To achieve high photocatalytic activity, TiO 2 nanoparticles require an excitation source in ultraviolet radiation. Incorporating chemical elements into the lattice can tune its band gap, resulting edge-shifted red absorption to reduce energies, improving performance visible region of electromagnetic spectrum. In this research, semiconductor were subjected a doping process using iron c...

Abstract The magnetocaloric effect based Magnetic refrigeration (MR) was considered a novel energy-efficient and environmentally benign cooling method. However, the lack of suitable magnetic solids has slowed development its practical applications. We herein fabricated RE 2 NiTiO 6 ( = Gd, Tb Ho) double perovskite (DP) compounds systematically determined their structural, properties by experime...

The structure, IR absorption, luminescence, and luminescence excitation spectra of La 0.98-x Lu x Eu 0.02 BO 3 orthoborates synthesized at 970 o C were studied 0≤ x≤0.98. An increase in leads to a sequential change the structural state orthoborates. At first, compound has aragonite structure. Then, it becomes two-phase contains vaterite phases. With further x, compounds have then calcite and, f...

Density functional theory (DFT) based calculations have been performed to examine the relaxations of tautomers of 4–hydroxy–6–methylpyridin–2(1H)–one (MPO), as a representative of pyridinone derivatives, at the fullerene (C60) surfaces. Optimized molecular properties including energies, dipole moments and atomic scale quadrupole coupling constants (CQ) have been e...
