Ion-implantation conditions and annealing effects for contiguous disk bubble devices

Iron implantation in gadolinium gallium garnet studied by conversion-electron Mössbauer spectroscopy

“…GGG can be grown in such a way as to provide excellent single-crystalline quality. Garnets were intensively studied in the 1980s with the aim of developing magnetic bubble devices [1][2][3][4]. Later on, ion implantation was used for doping garnets with various ions to prepare laser materials [5].…”

Annealing Effect in Hydrogen Atmosphere on Magnetic Properties of Ion-Implanted Yig Thin Films

“…Figure 2 shows AH,, AHo and AH, dependence on Ta in hydrogen atmosphere, [3] where AH, = H, -H,, H, is the resonance field of bulk YIG under the implanted layer, and AHo is the decrease of H, accompanied with the application of the field without light, respectively. AH, is also described as the anisotropy field change AHk [4]. A value of AH0 is determined at the time 60 min.…”

Local Magnetic Field and Positive Muon Diffusion in Yttrium Iron Garnet

“…The influence of ion implantation into YIG has been studied extensively from such view points [4][5][6][7][8][9]. The research revealed that hydrogen is one of the most efficient dopants to enhance the effective anisotropy field change of YIG films [4,8] and this beneficial effect fades away after annealing in a nitrogen atmosphere [7]. The latter behavior was attributed to out-diffusion of hydrogen from the YIG lattice.…”
