| contents | Magnetic phase diagram for the Hubbard model on the Beta-Mn type lattice has been calculated as a function of the Coulomb interaction energy parameter U and the electron number per atom n by using the generalized Hartree-Fock approximation combined with the recursion method for electronic-structure calculations. The ferromagnetic state, the ferrimagnetic state, and the helimagnetic state as well as the 3Q multiple spin density waves (3QMSDW) states have been obtained on the U-n plane. Their detailed structures are examined with use of the Fourier analysis. It is shown that the calculated phase diagram and the Dzyaloshinskii-Moriya interaction elucidate the magnetic interactions for the itinerant-electron skyrmions in transition metal alloys and compounds on the Beta-Mn type lattice. |
