摘要

We analyze the photo-induced carrier and magnetization dynamics in antiferromagnetic (AFM) HoMnO3 single crystals, delineated by wavelength-dependent femtosecond spectroscopy. The emergence of long-range and short-range magnetic order are unambiguously revealed in association with an abnormal blueshift of Mn3+ 3d level around the Néel temperature and the slope variation in the temperature-dependent transient reflectivity change (ΔR/R) near the Néel transition, respectively. Furthermore, the disturbance (in ps time scale) of the AFM ordering and its reordering time (in a few 100 ps time scale) are clearly identified in the negative ΔR/R.
