Dear Professor,

I am using AkaiKKR for the first time, i am trying to use AkaiKKR for Fe/Cu multilayers but it stopped quickly
and i have this error: err in chklat...inadequate rmt specified.
my in put file is:

Dear Professors,
Dear Hitoshi GOMI,
Thank you for your reply.
I applied your remark and it worked.
I have another question: I worked on the same system, but this time, i considered a face centered cubic structure for my Fe/Cu multilayers, I found a spin moment of iron equal to 0 for, all percentages of the iron or copper.

Is that logical? What's the cause ?
I have to act on what parameter?

Hello khadija chafai,

The crystal structure is specified by the combination of a Bravais lattice and a basis.
You set the bcc Bravais lattice, there are two lattice points; (0 0 0) and (1/2 1/2 1/2).
And you put the Fe_1Cu_1 at (0 0 0) position, which is duplicated to (1/2 1/2 1/2) position because of the bcc symmetry.
But you also put the Fe_2Cu_2 at (1/2 1/2 1/2), that is why the collision occurred.
