Building type 1, 2, 3 quaternary heusler alloy

[physics]

Hi everyone,

How to build type 1, 2, 3 quaternary heusler alloy with varying composition?

Thanks

I'd need you to elaborate on the type 1,2,3, as I am not familiar with that term, but building a basic quarternary Heusler alloy is very simple in the Builder.

1. Click the + button and open From Plugin>Crystal Builder.
2. The quarternary Heusler alloys belong to spacegroup 216
3. Insert the relevant atoms in Wyckoff positions 4a, 4b, 4c and 4d
4. Set the correct lattice constant.
5. Create the crystal

After that you can of course use the usual tools in the Builder to make supercells, substitute certain percentages of atoms with vacancies or other atoms, etc.

Hi,

Thank you for your reply. I want to know how to build quaternary heusler alloy of Y, L2, B2 and D0 type.

Thank you

There is a quite clear discussion on this in https://arxiv.org/pdf/1903.07265 for Y, L2_1 and B2.

I believe D0_3 is not a quaternary structure, but rather binary, of the type V3Si?
