[Wien] Magnetocrystalline anisotropy energy

2010-09-20 Thread Bin Shao
Dear all,

I intend to calculate magetocrystalline anisotropy (MCA) energy of the bcc
Fe monolayer. Since the MCA energy usually has an order of magnitude about
10^-6 eV, it's a tough work to get its calculated numerical value. The
reference PRB. *54*. 61 proposes a torque method and the MCA energy can be
easily evaluated through the expectation value of the angular derivative of
the spin-orbit coupling Hamiltonian at an certain angle with this method.
The paper gives an example of the free monolayer Fe using FLAPW method and
mentioned that "one only needs the self-consistent scalar relativistic
charge-spin density or potential and then performs one second-variational
calculation with the SOC hamiltonian invoked."

So, I want to know how to do this calculation, or to get the angular
derivative of the derivative of the spin-orbit coupling Hamiltonian  in
Wien2K.

Please give me some comments, thank you in advanced!

Best regards,

[Wien] termination of SCF cycle and "BAD HEADER" message in TiC problem

2010-09-20 Thread Varsha Goyal
Dear sir/mam,

 We are using wien2k10 .After successfully generating TiC.struct file and
initiallization when we run SCF cycle, it is terminated after one cycle only
and an error message "BAD HEADER" appears on the screen. Kindly suggest how
to get rid of this problem to compile successfully the SCF cycle and perform
various "Tasks" for the TiC .
Thanking you

[Wien] Slab convergence

2010-09-20 Thread Maxim Rakitin
  Dear Laurence,

Is *-noHinv* iterative mode available in WIEN2k 8 or 9? I don't see such 
option in 'runsp_lapw -h' list. There are only *-in* and *-in0* modes. 
I'd like to try the mode you suggested.

Thanks.

[Wien] trouble compiling WIEN2k

2010-09-20 Thread Maxim Rakitin
  Hi Chandrani and WIEN2k community,

I had the same problem when I compiled WIEN2k 10.1, and I haven't sorted 
it out either. I can open your attachment in my Thunderbird. The problem 
is with lots of similar warning messages like:
*W2kutils.c(131): warning #167: argument of type "void (*)()" is 
incompatible with parameter of type "__sighandler_t"
   signal ( SIGINT, w2ksignal_int );  /* Interrupt */*
******************************************
It's obvious that the problem is connected with C-routine W2kutils.c, 
and it cannot identify some parameters. The routine seems new or 
significantly modified, because I haven't seen the problem in previous 
versions of WIEN2k. Although there is no error, but these warning 
messages exist.
I suppose options tuning can help in this situation, but I'm not sure 
what exactly should be changed in OPTIONS file.

If somebody met the problem and found the solution of it, please share 
your experience with us.

Thanks a lot.
