Journal ArticleDOI
Cation disorder and size effects in magnetoresistive manganese oxide perovskites.
TL;DR: The ferromagnetic-metal-paramagnetic-insulator transition temperature varies as ${T}_m}={T}_{m}(0)\ensuremath{-}p{Q}^{2}$ due to strain fields resulting from ordered or disordered oxygen displacements $Q$ that are parametrized by the statistical mean and variance of the $A$ cation radius, respectively.
Journal ArticleDOI
Long range charge ordering in magnetite below the Verwey transition.
TL;DR: The crystal structure of Fe(3)O(4) below the 122 K Verwey transition has been refined using high-resolution x-ray and neutron powder diffraction data, giving direct evidence for charge ordering (CO) over four independent octahedral Fe sites.
Journal ArticleDOI
Structure and microstructure of the ferromagnetic superconductor RuSr 2 GdCu 2 O 8
TL;DR: In this paper, the average crystal structure is tetragonal at both 10 and 295 K, but a superstructure resulting from coherent rotations of the RuO 6 octahedra within subdomains of 50--200 \AA{} are observed by electron diffraction.
Journal ArticleDOI
Cation effects in doped La2CuO4 superconductors
TL;DR: In this paper, the critical temperature of (Ln1−xMx)2CuO4 superconductors was shown to decrease linearly with increasing A-site disorder, as quantified by the variance in the distribution of A site cation radii.

TL;DR: The vanadium oxyfluoride (DQVOF) is a geometrically frustrated magnetic bilayer material as discussed by the authors, whose structure consists of S = 1/2 kagome planes of V(4+) d(1) ions with s = 1 V(3+d+d(2) ions located between the KGome layers.
