Elemental magnetic moments and magnetic order in the S-doped Fe5GeTe2 van der Waals magnet

Fe5GeTe2 is one of the van der Waals ferromagnets with the highest Curie temperature. Its doping with S is known to induce magnetic easy-axis/easy-plane and ferromagnetic/antiferromagnetic transitions. Here, we propose to use X-ray magnetic circular dichroism (XMCD) and X-ray magnetic linear dichroism (XMLD) to determine the elemental magnetic moments and clarify the local magnetic order in S-doped Fe5GeTe2 thin films with various compositions.
