The dHvA oscillations for DySb is first detected for field direction rotated in the (001)-(111)-(110) plane. The magnetic field was swept from 65-97 kOe, which covered the ferrimagnetic structure with HoP-type and ferromagnetic state. The dHvA signals are quite different between both structures. The conduction-electron Fermi surface located at the Xz point was strongly reduced. It clearly shows that the interaction between the quadrupole moment and the conduction electrons strongly affects the Fermi surfaces for DySb compared to the other RSb.
