Nanostructure-driven complex magnetic behavior of Sm2CoMnO6 double perovskite

Structural, magnetic and optical properties of disordered double perovskite Gd2CoCrO6 nanoparticles

“…The deconvolution peaks of Co-2p 3/2 at binding energies of 780.22 eV and 784.49 eV represent the Co 3+ and Co 2+ states, respectively, and the deconvolution peak of Co-2p 1/2 at 795.78 eV represents the Co 3+ state. 59,60 Similarly, the XPS spectrum of the Cr element also exhibits spin–orbit splitting at 575.88 eV and 585.85 eV, which correspond to the 2p 3/2 and 2p 1/2 states, respectively. Further deconvolution of state 2p 3/2 at 575.54 eV and 576.98 eV reveals the presence of mixed states Cr 2+ and Cr 3+ , respectively, and deconvolution of state 2p 1/2 at 585.68 eV and 586.88 eV represents the mixed state of Cr 3+ and Cr 6+ states.…”

Expansion of the multifunctionality in off-stoichiometric manganites using post-annealing and high pressure: physical and electrochemical studies

“…[68][69][70][71][72][73] It makes them promising materials for practical applications with the possible adaptation for magnetic refrigerators, magnetic and electric field sensors, and nonlinear optical systems. 38,74,75 Such large values of the MCE in LMO-1150 exhibit an optimal order/disorder ratio caused by, on the one hand, the conventional DE via Mn 3+ 2 O 2À 2 Mn 4+ and multiple DE via Mn 3+ 2 O 2À 2 Mn 2+ 2 O 2À 2 Mn 4+ , 28 and, on the other hand, the structural defects and distortions. 40 In all other samples, the MCE decreases with an increase in t ann due to the enlargement of structural heterogeneities.…”

Ground-state structure, orbital ordering and metal-insulator transition in double-perovskite PrBaMn2O6

“…These properties can be further improved and tuned by fabricating double perovskite structures with general chemical formula AA'BB'O 6 (where A/A' are alkaline/rare earth metals, B/B' are transition/nontransition metals). Due to differences in atomic radii of A/A' and/or B/B' ions and possibility of their ordering in alternating perovskite layers, such compounds demonstrate complicated behavior and can serve as a basis for new multifunctional materials [5][6][7][8][9][10][11][12][13][14].…”
