[Wien] Heusler Alloy Fe2CrSn_Atomic Position
Dear Wien2k Users, I am trying to calculate the electronic structure of Heusler alloy Fe2CrSn using Wien2k. It is supposed to exist in L2/1 structure (space group 225) with following positions: Fe: 0.25 0.25 0.25 Fe: 0.75 0.75 0.75 Cr: 0.5 0.5 0.5 Sn: 0.0 0.0 0.0 When the positions are changed as follows: Fe: 0.0 0.0 0.0 Fe: 0.5 0.5 0.5 Cr: 0.25 0.25 0.25 Sn: 0.75 0.75 0.75 then the Wien shows space group 216 and magnetic properties are totally changed. Is it right and what is the excact structure for Fe2CrSn? Please help me. Thanks in advance, -- Alpa Dashora -- next part -- An HTML attachment was scrubbed...

[Wien] Error in mixer file
Dear Laurence Marks, Thank you very much for your reply. today I found the same problem with a simple calculation at the time of initialisation. At third iteration, the program stopped with the same error. I didn't change and save any file during this run. I am using WIEN2k_09.1 (Release 5/2/2009) version. By the way, I did not understand what you want to mean by telling "ensure that you are using the latest mixer (update if needed)". Thanking you again.

[Wien] Error in mixer file
Please download the very latest version from the web page and compile it -- to ensure that this is not an issue (some updates go directly onto the web page prior to a new release). This will remove ambiguities so we know exactly what you are using. If there is still a problem and you cannot cure it by deleting the *broyd* files and continuing please let me know (perhaps use my direct email). 2009/9/8 Debojyoti Mukherjee : > Dear Laurence Marks, > > ?

[Wien] Heusler Alloy Fe2CrSn_Atomic Position
Hello, the position (1/4, 1/4, 1/4) has eightfold symmetry in space group 225, one of the equivalent positions being (3/4, 3/4, 3/4). Thus, Fe should only be specified once - does this solve the problem?

[Wien] Heusler Alloy Fe2CrSn_Atomic Position
For the 2 structures below, the result should be the same. as in space group 216 the change of the atoms in positions 4a, 4b with those on 4c,4d results in the same symmetry (all positions have Td symmetry) Occupying 4a,4b or 4c,4d (like you gave below) with the same species will always result in a higher symmetry (Oh) for the other two positions, and thus into space group 225. If the Fe atoms have an antiparallel coupling then (as this is not possible in 225) the result of 216 will be different, otherwise it is identical. If you exchange in a way that you have for example Fe: 0.25 0.25 0.25 Cr: 0.75 0.75 0.75 Fe: 0.5 0.5 0.5 Sn: 0.0 0.0 0.0 then this is different from the structures you gave, and indeed, the magnetic behaviour will be different. The "exact" structure should be the one with lowest total energy, trivially. Ciao Gerhard EVERYTHING IS SYMMETRY IS EVERYTHING Dr. Gerhard H.

[Wien] to PBS from w2web
Hi, I have arrived to a point where I am ready to submit the test job. I created the job using w2web. The problem is I am using PBS for all of my jobs. Is there an option to submit to PBS que straight from the w2web dialog? I am pretty sure there is but I am novice at WIEN2k. If there is no way to submit it, shall I just use a simple PBS script as described here, http://www.wien2k.at/reg_user/faq/pbs.job after I click "only save parameters" dialogue? thanks JOnas
