Creating an interlayer DMI simulation

[Sagar-jpg-afk]

Hello Team,
I want to run a simulation of an synthetic antiferromagnetic stack, with interlayer RKKY and interlayer DMI interactions. I am able to add the RKKY term but I cant find a way to add the interlayer DMI term. Also would it be possible to arbitrarily define a DMI vector, as I would like to study the variation of characteristics with varying DMI vector.

Thank you in advance.

Regards,
Sagar
