Abstract

The first known quantitative measurements of an ultrafast relaxation process in yttrium iron garnet (YIG) are presented. Decay out of the initially excited crystal field state at 16 000 cm−1 was observed to occur in 100 ± 40 fsec. Additional measurements performed on YGG:Fe (Y3Ga4.8Fe0.2O12) at 298 and 2.6 K implicate the involvement of charge-transfer states in this ultrafast relaxation. Lifetimes of less than 2 fsec are indicated for pure charge-transfer states. No dynamic manifestation of the strong antiferromagnetic exchange coupling between iron ions in YIG is evident.

Induced absorbance change at room temperature in YIG versus delay time. Pump and probe pulses are 0.18 psec FWHM, at 625 nm, and polarized parallel (solid line) or perpendicular (dotted line) with respect to each other. A numerically modeled fit (circles) to the parallel data yields a characteristic lifetime for the initially prepared state of 100 ± 40 fsec.
