الوصف: | Insulating 5d3 La3OsO7 and hole doped La2.8Ca0.2OsO7 materials featuring well separated pseudo-one-dimensional zig-zag chains of corner-sharing OsO6 octahedra have been synthesized and their magnetic and electrical transport properties characterized. Long range magnetic order between the antiferromagnetic chains is determined with a propagation vector k = 1/2, 1/2, 0 and TN = 45 and 53 K for the parent and doped materials. An Os5+ moment of 1.7(1) {\mu}B for La3OsO7 and 1.2(2) {\mu}B for La2.8Ca0.2OsO7 is refined. The long range magnetic structure is compared to the few currently known for isostructural Ln3MO7 compounds. Comment: 15 pages, 6 figures |
