Dear Users, I am trying to calculate the full phonon spectrum of a ferromagnetic alloy but the results that I found are not matching with literature. So I want to know
(1) How to assign 110-direction for a grid calculation? (2)Whether calculating phonon spectrum from Gamma to X point along 110 direction is the same as that of a single point calculation at 110 point for this particular point. (3)Will both calculations give the same frequencies at 110 point? (4)My phonon spectrum do not match previous papers. Is there anything to do with grid size?(I used 4X4X4 Monkhorst pack ) If anybody throw me some light on these questions, i will be very happy. Thanking you in advance SATYANAND CH Junior Research Fellow Department of Physics Gauhati University Guwahati 781014 (+91)950-895-6853 email: csatya11 at gmail.com me as that of a single point calculation at 110 point.
