چکیده
Recent discoveries of novel physics in two-dimensional (2D) magnetic materials have sparked the search new layered semiconductors. Compared to traditional inorganic 2D van der Waals crystals, hybrid organic–inorganic metal–halide frameworks offer significantly enhanced chemical and structural versatility, where their optical, electronic, properties can be readily modulated with both organic components. Here, we reported a series Fe–Cl-based double perovskites LnMIMIIICl8, [n = 4, L phenylethylammonium or chiral R-(+)-β-methylphenethylammonium n 2, 1,4-butanediammonium; MI Ag/Na; MIII Fe/In]. UV–vis measurements show that optical band gaps are highly tunable by varying cations, ion, ion. Magnetic susceptibility suggest an antiferromagnetic coupling between nearest FeIII–FeIII, Curie–Weiss temperature, Néel frustration factors easily compositions dimensionality. Our study demonstrates rich interesting these transition-metal–halide paves way for design multifunctional materials.

Coulomb correlation and magnetic ordering in double-layered manganites: LaSr2Mn2O7
A detailed study of the electronic structure and magnetic configurations of the 50% hole-doped double-layered manganite LaSr2Mn2O7 is presented. We demonstrate that the on-site Coulomb correlation (U) of Mn d electrons (i) significantly modifies the electronic structure, magnetic ordering (from FM to AFM), and interlayer exchange interactions, and (ii) promotes strong anisotropy in electrical t...
متن کاملStructure for perovskites with layered ordering of A-site cations.
The structure of La(1/3)NbO3 is that of a perovskite with La3+ cations ordered into alternate layers of perovskite A-sites. This is the description of a tetragonal structure and yet the room-temperature structure shows an orthorhombic distortion. The structure of La(2/3)TiO3 shows similar features. It has been recognized only very recently that the orthorhombic distortion in both these compound...
متن کاملInvestigation of effect of magnetic ordering on structural and electronic properties of double perovskites Sr2BWO6 (B = Co, Ni, Cu) using ab initio method
Structural and electronic properties of double perovskites Sr2BWO6 (B = Co, Ni, Cu) were studied for each of three magnetic configurations nonmagnetic, ferromagnetic, and antiferromagnetic by using density functional theory in generalized gradient approximations (GGA) and strong correlation correction (GGA + U). Due to magnetic transition from antiferromagnetic to nonmagnetic phase, an electr...
متن کاملIntrinsic white-light emission from layered hybrid perovskites.
We report on the second family of layered perovskite white-light emitters with improved photoluminescence quantum efficiencies (PLQEs). Upon near-ultraviolet excitation, two new Pb-Cl and Pb-Br perovskites emit broadband "cold" and "warm" white light, respectively, with high color rendition. Emission from large, single crystals indicates an origin from the bulk material and not surface defect s...
