Element Selected Spin-Dependent d-d Charge Transfer Transitions in Bi2FeMnO6 Film: An Ultrafast Pump-Probe Study
Source abstract
Abstract
The ultrafast optical response of the magnetic compound Bi2FeMnO6 (BFMO) is studied through 100–300 K by means of ultrafast transient reflectivity spectroscopy. By using differing pump energy, the optical low spin (LS) transition and high spin (HS) transition in this compound are distinguished as the temperature varies. This charge transfer transition is shown to be spin-dependent and element selected. The ultrafast spin-lattice coupling time also shows the element selected feature, which illustrated the two independent magnetic phase transitions to the antiferromagnet (AFM) Mn–O–Mn and the ferrimagnet (FIM) Mn–O–Fe order, respectively.
