Synthesis, structural, magnetic and transport properties of layered perovskite-related titanates, niobates and tantalates of the type AnBnO3n+2, A′Ak−1BkO3k+1 and AmBm−1O3m
TL;DR: In this paper, a comprehensive overview on the title oxides and their properties is presented, with emphasis on electrical conductors, with a special feature of the quasi-1D metals of the type AnBnO3n+2 is their compositional, structural and electronic proximity to nonconducting (anti)ferroelectrics.

A profile refinement method for nuclear and magnetic structures
TL;DR: In this paper, a structure refinement method was described which does not use integrated neutron powder intensities, single or overlapping, but employs directly the profile intensities obtained from step-scanning measurements of the powder diagram.
