fullprof program window refresh

2020-04-16 Thread alberto . martinelli
Dear all, I'm using Fullprof. After starting the refinement, the "fullprof program" window opens showing the progress of the calculation. Unfortunately, if I change the window during the calculation (for example for checking e-mail) and then come back to fullprof, the "fullprof program" windo

slits in X’Pert PRO

2021-03-24 Thread alberto . martinelli
Dear all, my laboratory recently inherited an old X’Pert PRO diffractometer. Previous owners labelled some of the slits as FDS (Fixed Divergence Slit) or FASS (Fixed Anti-Scatter Slit), but most of the slits have no label. Actually, I cannot see any evident difference between FDS, FASS and ot

"Full Physically Irreps" option in BasIreps

2021-11-12 Thread alberto . martinelli
Dear all, I'm calculating the possible magnetic orderings using BasIreps (Fullprof). In particular I'm analyzing the possible orderings with k=(0,0,0.5). What concerns me is that when I select/deselect the "Full Physically Irreps" option the calculated magnetic structures are different. For

Dear all, I'm following this interesting discussion. It seems to me that sometimes there is an improper use of terminology, in particular when we talk about "profile refinement"; in reality, we all know that it is about "profile fitting". Or did I miss something? sorry for the pedantry. Albe

Dear all, I'm refining a crystal structure with Pnma space group using Fullprof; since it appears strained I refined also the microstructural parameters using strain model=3. my questions are: 1) are negative values meaningful or only positive values must be considered? 2) what is the unit of measu

magnetic structure defined by 2 or more irreps

2025-07-12 Thread alberto . martinelli
Dear all, I am looking for cases in the literature in which at least 2 different irreducible representations are necessary to describe the magnetic structure at the same atomic site. Specifically, I mean that the atomic site must be the same in the magnetic cell; that is not the case where t
