“…It is known that non-Ho DP compounds, such as Gd 2 NiMnO 6 and Gd 2 CoMnO 6 exhibits significant MCE at low temperatures, with – Δ S values of 35.5 J kg −1 K −1 and 24 J kg −1 K −1 , respectively, for H = 0–7 T. 30 In a study by Zhang et al 31 cryogenic magnetic properties and magnetocaloric effect in Pr 2 NiMnO 6 and Pr 2 CoMnO 6 compounds, reporting the second-order phase transition with −ΔS values of 3.15 at 208 K and 3.91 J kg −1 K −1 at 170 K under an applied field of 7 T. In our previous work, 32 we reported that the varying the B-site in double perovskite materials prepared by solid-state reaction with different transition metal elements results in variation of Curie temperature. Li et al 33 recently published a study on the effect of B′-site ordering on magnetocaloric and critical behavior in Nd 2 BMnO 6 with B = Ni and Co.…”

“…In addition, the magnetization-temperature dependence curve of Ho 2 CoMnO 6 exhibits ferromagnetic features at low temperatures and purely paramagnetic at high temperatures. In addition, several of experimental studies that included Ho 2 CoMnO 6 and other compounds were achieved in these literatures [8][9][10].…”

The density functional theory as a computational approach was used to explore the ferrimagnetic semiconducting behavior of Dy2CoMnO6 double perovskite compound in both spin-up and spin-down directions. Thermodynamic stability was confirmed in a wide pressure range set to 30 GPa. Both scalar and full relativistic calculations are used to estimate the spin-orbit effect. The topological distribution of the charge density and the net effective charge of each atom are studied based on the Quantum Theory of Atoms in Molecules (QTAIM) as implemented in Bader code, Besides this, the different QTAIM atomic basins descriptors such as electron density ρ_b, Laplacian of the electron density ∇^2 ρ_b, potential electronic energy density V_b, kinetic electronic energy density G_b and density of the total electronic energy H_b at bond critical points (BCPs) are estimated using CRITIC2 software where the ionic type for Dy-O, Co-O, and Mn-O bonds are evaluated. Holes and electrons have different effective masses, their thermoelectric properties appear high figure of merit (ZT) exceeding 0.5 for temperatures greater than 500 K in the negative chemical potential region, suggesting that doping with holes might be more favorable for thermoelectric efficiency than doping with electrons.

Ordered double perovskite La2FeCrO6 nanoparticles (NPs) were synthesized via the citrate auto-combustion technique. The prepared sample was characterized by X-ray diffraction (XRD), energy dispersive X-ray analysis (EDAX), and Raman spectroscopy, which confirmed the double perovskite structure of the studied sample. XRD illustrated that the investigated sample has an orthorhombic structure with an average crystallite size of 25.3 nm. La2FeCrO6 NPs exhibit a porous structure and spongy morphology, as determined through analyses using Brunauer–Emmett–Teller (BET) specific surface area and field emission scanning electron microscopy (FESEM). The studied sample exhibits anti-ferromagnetic (AFM) behavior with weak ferromagnetic (FM) components, as an example of d5(Fe3+)–d3(Cr3+) systems. The AFM behavior is caused by the super-exchange interaction between [Fe3+(d5)–O–Cr3+(d3)], according to the Kanamori–Goodenough (KG) rule. This behavior is induced by the pdπ hybridization between the eg orbital of the transition metal and the pσ orbital of the oxygen, while the one induced by the pdσ hybridization is FM. The number of excited-state configurations mediated by the pdπ hybridization in the Fe–Cr pair is greater than that mediated by pdσ hybridization. Pb(II) heavy metal ions are used in adsorption studies. The electrostatic nature of the bonding between Pb(II) and the La2FeCrO6 nano ferrite sample is thought to be the main cause of the observed high sorption of La2FeCrO6 to a Pb(II) ion. La2FeCrO6 has a favorable morphology, which bodes well for its prospective applications in Li-ion batteries, water purification, and gas sensors.
