Investigation 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 کاملUmbrella stoichiometry: a guide to the solid state chemistry of copper-rich oxides
Umbrella stoichiometries are relatively unstable compositions that can be leveraged to promote the formation of unconventional solid III II VI V V state structures. La and Cu in a one to one ratio is such a stoichiometry. The addition of a third metal such as Mo , V , or Ru generates a complex set of potential products. Nonetheless, La Cu MoO forms a single phase because no low energy multiphas...

متن کاملCrystal structure and optical and magnetic properties of Pr(2)(MoO(4))(3).
Praseodymium molybdate Pr(2)(MoO(4))(3) was synthesized using the standard ceramic route. The crystal structure of the material has been successfully solved in superspace group I2/b(alphabeta0)00 with lattice constants a = 5.30284(4), b = 5.32699(3), c = 11.7935(1) A, gamma = 90.163(1) degrees , and the modulation vector q = 2/3a* + 0.88810(2)b*. The deviation of the q vector from a rational va...
متن کاملSlow antiferromagnetic dynamics in the low temperature tetragonal phase of La 2 − x Sr x CuO 4 as revealed by ESR of Gd spin probes
Slow antiferromagnetic dynamics in the low temperature tetragonal phase of La 2−x Sr x CuO 4 as revealed by ESR of Gd spin probes Abstract Measuring the ESR of Gd spin probes we have studied the magnetic properties of the copper oxide planes in the low temperature tetragonal (LTT) phase of Eu doped La 2−x Sr x CuO 4. The data give evidence that at particular levels of Sr and Eu doping the frequ...
