Re: [Wien] How to set the occupation number in Wien2k?

You showed the :qtl line for spin-dn, with a 4f occupation of 0.1000. There is another line above, which gives spin-up. Could it be that you get a non-magnetic solution without field ? Is the dmat from a plain GGA or a GGA+U calculation ? The application of a magnetic field for 4f systems can b

Hi. I'm a college student interested in WIEN2k. My WIEN2k's version is 14.2. I've used this simulation for a month. I have majored in electronic engineering. but sadly i am not good at solid state physics. To make matters worse, i'm not good at English too. so, i really need your kind helps. the

Youngbeam, there are a tremendous number of things one can do with WIEN2K or other reliable DFT codes such as VASP etc - band gaps and transport properties of semiconductors, magnetic materials including magnetization, magnetic anisotropy and Curie temperature, etc - the list is almost endless.

The QTL numbers are only within the RMTs, some of the spin is in the interstitial region. It is hard to force occupations in Wien2k, the most you can do is set a starting point, and hope that the scf iterations converge to what you are interested in. --- Professor Laurence Marks Department of Mate

Then the dmat and the scf-files do not fit together ! I've noted myself that sometimes the mixer does not properly "mix" the dmat files, i.e. the new dmat files and the mixed ones disagree and do not converge to the same numbers. To check if this happens in your case: compare the dmats of ca
