Optical absorption spectra corresponding to the2F7/2→ 2F5/2 transition of Yb3+ in YbCrO3were investigated under high magnetic fields. The energy positions ofthese spectra remarkably changed at the metamagnetic transition wherethe weak ferromagnetic moment of the Cr3+ spins reverses itsdirection. From the analysis of the spectral change at the transition, the microscopic mechanism of the metamagnetic transition wereelucidated. In the energy region of the 2F7/2→2F5/2 transition of Yb3+, besides single-ion excitations, cooperative absorption spectra corresponding to the Yb3+ excitoncoupled with Cr3+ magnon and the Yb3+ exciton coupled withYb3+ spin-flip were observed. From the analysis of thesecooperative absorption spectra, the behavior of the Cr3+ magnonmode and the Yb3+ spin-flip mode under high magnetic fields wasinvestigated.
