Zusammenfassung
We compare the ultrafast dynamics of the spin reorientation transition in the orthoferrite Sm0.7Er0.3FeO3 following two different pumping mechanisms. Intense few-cycle pulses in the midinfrared selectively excite either the f−f electronic transition of Sm3+ or optical phonons. With phonon pumping, a finite time delay exists for the spin reorientation, reflecting the energy transfer between the lattice and 4f system. In contrast, an instantaneous response is found for resonant f−f excitation. This suggests that 4f electronic pumping can directly alter the magnetic anisotropy due to the modification of 4f−3d exchange at femtosecond timescales, without involving lattice thermalization.
