[Wien] Heusler alloy in presence of external magnetic field

[shamik chakrabarti]

Dear Peter & Gerhard,

                 Thank you for your replies. We have edited the .inorb file
accordingly & the simulation is now running smoothly. Yes, we have a plan
to increase Bext in steps and to observe its effect on density of states.

Thank you once again.

with regards,
