Request for Help with CrSb Altermagnet Simulaition in Vampire

[Talha Mahamud]

Hello Vampire users,

I am currently working with the altermagnet CrSb and facing some difficulties in reproducing the spin rotation described in a paper I will attach to this email. Specifically:

• I am attempting to reproduce the rotation of spin as outlined in the attached paper (see Section Note-6 for spin dynamics).
• I have created both a .mat and a .ucf file, but unfortunately, they are not working as expected.
• I will attach these files along with the paper for your reference.

My main question is whether there are any additional setup requirements for simulating altermagnets in Vampire. Any guidance or suggestions to help resolve this issue would be greatly appreciated.

Thank you for your time and support.
Best regards, Talha Mahamud
