Influence of chemical ordering on magnetocrystalline anisotropy and magnetoelastic properties in Weyl magnetic semimetal Co2MnGa thin films
Source abstract
Abstract
The magnetic anisotropy and magnetoelastic properties of the magnetic Weyl semimetal Co 2 MnGa were investigated in the Co 2 MnGa thin films with different chemical orderings. Their properties change, in line with the increase in the contents of the highly-ordered B2 and L2 1 phases. The most significant changes of both the magnetic anisotropy and the magnetoelastic properties were correlated with the appearance of the L2 1 ordered phase of Heusler alloy, which is also responsible for topological properties of these compounds. The magnetoelastic properties of L2 1 ordered Co 2 MnGa are discussed in comparison with the Co 2 Fe x Mn 1-x Si system with a similar degree of ordering, which has similar crystallographic structure but it is not Weyl semimetal. In particular, significant differences between the magnetoelastic properties of ordered Co 2 MnGa and Co 2 MnSi were found. In the case of L2 1 -ordered Co 2 MnGa, the giant anisotropy of the magnetoelastic properties was observed.
