Pressure effect on the Fermi surface and electronic structure of LuGa3 and TmGa3

• The Fermi surfaces and cyclotron masses of LuGa3 and TmGa3 compounds are Studied by means of the de Haas-van Alphen effect, technique under pressure. Highly anisotropic pressure dependences of the de Haas-van Alphen frequencies and cyclotron masses are observed ill both compounds. Concurrently, ab initio calculations of the volume-dependent band structures are been carried out for these compounds, including the ferromagnetic-configuration phase of TmGa3, by employing a relativistic version of the full-potential linear muffin-tin orbital method within the local spin-density approximation. The experimental data are analyzed oil the basis of the calculated volume-dependent hand structures and compared with the corresponding pressure effects in the isostructural compound ErGa3.
