Crystal structure and magnetism in CoSb2O6 and CoTa2O6
TLDR

Recent advances in magnetic structure determination by neutron powder diffraction
TL;DR: In this article, the main formulas governing the analysis of the Bragg magnetic scattering are summarized and shortly discussed and the method of profile fitting without a structural model to get precise integrated intensities and refine the propagation vector(s) of the magnetic structure is discussed.

Revised effective ionic radii and systematic studies of interatomic distances in halides and chalcogenides
TL;DR: The effective ionic radii of Shannon & Prewitt [Acta Cryst. (1969), B25, 925-945] are revised to include more unusual oxidation states and coordinations as mentioned in this paper.

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.

New Approach to the Theory of Superexchange Interactions
TL;DR: In this article, the theory of indirect exchange in poor conductors is examined from a new viewpoint in which the $d$ (or $f$) shell electrons are placed in wave functions assumed to be exact solutions of the problem of a single $d-electron in the presence of the full diamagnetic lattice.

Relation between the specific heat and susceptibility of an antiferromagnet
TL;DR: In this paper, it was shown by a general theoretical argument that the variation of the magnetic specific heat of a simple antiferromagnet, in particular the singular behavior in the region of the transition, should be closely similar to the behaviour of the function ∂(χT)∂T, where χ is the zero-field susceptibility.
