Resolution of the incommensurate contributions to the magnetic propagation vector in Mn2InNbO6 and Mn2InTaO6
Mn2InNbO6 and Mn2InTaO6 have recently been studied. D20 data collected at low temperatures reveal their different thermal evolution, where the niobate develops a simple AFM structure with k = [0 0 0] but an incommensurate structure competes at low temperature in the tantalate. The incommensurate contribution does not fit a simple [0 0 kz] propagation vector from the 2K-30K difference pattern, but an additional kx contribution is required. However, the use of the standard 2.42 A and 2.45 A wavelengths at D20 and XtremeD respectively does not allow to fully resolve the satellites arising from the short kx contribution. For this reason, an EASY experiment is requested to collect a long scan at 2K using the longer 3.8 A wavelength. This will enable the complete splitting of the two different sets of satellite peaks around (101) nuclear peak, which remain convoluted in the preliminary data. Nb is similar to Ta by all means, so the two isostructural compounds are expected to show a similar behaviour. Collecting data on XtremeD using the mentioned long wavelength will confirm this similarity.
