| contents | The magnetic anisotropy and magnetoelastic properties of the magnetic Weyl semimetal Co2MnGa were investigated by exploiting the Co2MnGa thin films with different chemical orderings. The epitaxial layers were grown by sputtering directly on MgO (001) and the annealing temperatures after the deposition were varied, which allowed us to change the chemical ordering of Co2MnGa. We observed a clear relationship between the annealing temperature and the parameters of magnetic property. The most significant changes of both the magnetic anisotropy and the magnetoelastic properties were correlated with the appearance of the L21 ordered phase, suggesting that the emergence of magnetic Weyl semimetallic feature is the key point to vary these magnetic properties. |
