Abstract

A magneto-optical chip of Fe-(Co{sub 6}Ag{sub 94}) granular films was fabricated by using of combinatorial Fe ions implanting into co-sputtered Co{sub 6}Ag{sub 94} films and 16 units with different Fe content were prepared via binary masking scheme. The structures and surface morphologies of as-prepared and annealed Fe-Co{sub 6}Ag{sub 94} films were analyzed by X-ray diffraction and atomic force microscopy respectively. It reveals that the Co, Fe and FeCo granules precipitate, grow and then form nanoparticles embedded in the Ag matrix during annealing. In addition, the measurement of the magneto-optic polar Kerr effect shows that Kerr rotation increases with increasing Fe content, which contributes to the magnetic moment. Precipitation and growth of the magnetic granules during annealing also increase the Kerr rotation due to the size effects. Further, Moessbauer study confirms that the formation of granules with certain size plays a principal role in the enhancement of magneto-optic polar Kerr effect.

Dependence of the polar Kerr angle and coercivity on repeat distance in sequentially prepared Tb/FeCo films

Journal Article Shin, S - Journal of Applied Physics; (USA)

Multilayer thin films of Tb and FeCo were prepared by sequential thermal evaporation of Tb and Fe{sub 90}Co{sub 10} alloy on glass substrates at ambient temperature in a vacuum of about 1 {times} 10{sup {minus}6} Torr. The repeat distance of the films was varied from 3.5 to 175 A while maintaining the composition constant for all samples. Low-angle x-ray diffraction and Auger electron spectroscopy showed that a multilayer structure was achieved for films fabricated with a repeat distance {Lambda}{ge}31.5 A. The polar Kerr rotation angle and coercivity of the samples were obtained by measuring the polar Kerr hysteresis loop usingmore »« less

X-ray magneto-optic Kerr effect studies of spring magnet heterostructures

Conference Kortright, J; Kim, Sang-Koog; Fullerton, E; ...

The complex 3-dimensional magnetization reversal behavior of Sm-Co/Fe exchange spring films is used to test the sensitivity of different resonant soft x-ray magneto-optical Kerr effect (MOKE) measurements to changes in longitudinal and transverse moments within the soft Fe layer and to changes in these moments in depth within the Fe layer. As in the visible MOKE, changes in longitudinal and net transverse moments are resolved by measuring both Kerr rotation and intensity loops, respectively, near the Fe 2p core resonance. These x-ray MOKE signals measured using linear incident polarization are more directly interpreted in terms of longitudinal and transverse momentsmore »« less

Observation of a metamagnetic phase transition in an itinerant 4f system via the magneto-optic Kerr effect: Ce(Fe{sub 1-x}Co{sub x}){sub 2}

Journal Article Lange, R; Fisher, I; Canfield, P; ... - Physical Review. B, Condensed Matter and Materials Physics

The optical and magneto-optical properties of single crystals of YFe{sub 2}, CeFe{sub 2}, and Ce(Fe{sub 1-x}Co{sub x}){sub 2} (x{approx_equal}0.1) were measured between 1.4 and 5.0 eV using a rotating-analyzer ellipsometer and a normal-incidence polar Kerr spectrometer. The electronic structures and optical properties of YFe{sub 2} and CeFe{sub 2} were calculated using the tight-binding linear muffin-tin orbital method in the atomic-sphere approximation. For YFe{sub 2} the calculations reproduce the experimental spectra. Alloying CeFe{sub 2} with small amounts of Co leads to an electronic instability which is evidenced by a low-temperature antiferromagnetic (AF) phase. The Kerr effect was measured in the AFmore »« less

Observation of reversed hysteresis loops and negative coercivity in granular GaAs{endash}Fe hybrid structures

Journal Article Fumagalli, P; Sommer, G; Lippitz, H; ... - Journal of Applied Physics

We have studied GaAs{endash}Fe granular magnetic-semiconductor hybrid structures by magneto-optic spectroscopy in a photon-energy range from 0.7 to 5 eV at temperatures from 7 to 300 K in magnetic fields up to 1.8 T. The structures have been grown by alternative molecular-beam deposition of GaAs and Fe. At the chosen substrate temperature of T{sub s}=580{degree}C the Fe precipitates into clusters of nanometer to submicron size which are in part ferromagnetically ordered at 300 K. The polar Kerr spectra at 300 and 7 K show for the hybrid structures with high Fe content a broad negative peak with a Kerr rotationmore »« less
