Abstract

The splitting wave form of Shubnikov-de Haas and de Haas-van Alphen oscillations has been well known to appear in the antiferromagneticlike organic conductor α-(BEDT-TTF)2KHg(SCN)4. We have studied in detail how the separation ratio of the splitting wave form depends on the magnetic field and its orientation. In comparison of these measurements with previously proposed models, it is found that the spin-splitting model taking a positive exchange interaction into account can uniquely explain these results in a consistent way. The physical origin of this positive exchange interaction is discussed from the spin-density-wave picture.
