Abstract: Abstract The synthesis, structures, and magnetic properties are reported of three new polynuclear FeIII complexes containing the anions of picolinic acid (picH) and triethanolamine (teaH3) as chelates. The complexes [Fe6O2(OH)2(O2CR)4(pic)4(teaH)2] (R = Me (1), Ph (2)) and… read more here.

DOI: 10.1103/physrevb.103.024426
Abstract: Using density functional theory together with Monte Carlo simulations, we demonstrate that epitaxial strain, both compressive and tensile, attenuates the spin frustration of double perovskite ${\mathrm{Sr}}_{2}\mathrm{Fe}\mathrm{Os}{\mathrm{O}}_{6}$ to significantly enhance the critical temperature to 310 K,… read more here.
