Time-resolved photo-magnetic switching of bubble domains in ferrimagnetic garnets

چکیده
We investigate the single-domain switching of magnetization with a femtosecond laser pulse in Co-doped iron garnet films using time-resolved magneto-optical imaging. This regime is achieved pump fluence that two times lower than required for multi-domain switching. observed picoseconds dynamics single bubble domain diameter few micrometers by tuning fluence. may provide opportunities cold photo-magnetic recording magnetic bits approaching nano-size scale.

Time Resolved Excited State Photo-Engineering
This thesis concerns the development and application of time resolved fluorescence which yield new and detailed information on molecular order and motion in both isotropic and ordered systems. Polarised fluorescence studies involve the photoselection of a non-equilibrium distribution of excited state probe orientations whose relaxation is monitored by time resolved fluorescence anisotropy.

متن کاملTitle: Conformal Lattice of Magnetic Bubble Domains in Garnet Film
We report experimental observations of magnetic bubble domain arrays with no apparent translational symmetry. Additionally the results of comparative numerical studies are discussed. Our goal is to present experimental evidence for natural occurrence of conformal structures.
متن کاملMagnetic Properties of Y3−2xCa2xFe5−xVxO12 Garnets
A comprehensive study of the magnetic properties of Y3−2xCa2xFe5−xVxO12 (0 ≤ x ≤ 1) has been performed. The garnet ferrites samples were prepared by the ceramic technique, and X-ray diffraction analysis indicates the formation of single cubic phase. Vibrating sample magnetometry (VSM) and a superconducting quantum-interference device (SQUID) were used to measure the magnetic properties, especia...
متن کاملTime resolved MARY spectra in the photo cleavage of TMDPO
The time resolved feature of the MARY (Magnetic field effect on Reaction Yield) spectra is studied in the system of Diphenyl(2,4,6-trimethyl-benzoyl)phosphineoxide (TMDPO) in micelle. Two kinds of magnetic field effects (MFE) can be distinguished in the different time scales. First one is generated in the time scale less than 50 ns and negative (decrease the transient absorption in comparison w...
متن کاملCurrent-induced switching of domains in magnetic multilayer devices
Current-induced switching in the orientation of magnetic moments is observed in cobalt/copper/cobalt sandwich structures, for currents flowing perpendicularly through the layers. Magnetic domains in adjacent cobalt layers can be manipulated controllably between stable parallel and antiparallel configurations by applying current pulses of the appropriate sign. The observations are in accord with...
