BixY3−xFe5O12 thin films prepared by laser ablation for magneto-optical imaging of superconducting thin films

Curie temperature, exchange integrals, and magneto-optical properties in off-stoichiometric bismuth iron garnet epitaxial films

“…1 and references therein͒. Apart from the obvious interest of these Bi-substituted compounds in view of applications, [2][3][4][5][6][7][8][9] there has also been much attention paid to the theoretical aspects ͑see Ref. 10͒ especially concerning the influence of Bi on the spectral dependence of the magneto-optical properties.…”

“…[11][12][13][14][15][16][17][18][19] However, studies on the role of bismuth in iron garnets have long been confined to compounds with relatively low bismuth content because the pure bismuth iron garnet Bi 3 Fe 5 O 12 ͑BIG͒ does not exist in bulk form ͑due to the large ionic radius of the Bi 3+ cation͒ and cannot be grown by liquid-phase epitaxy ͑LPE͒. Since 1989, several authors have shown that BIG can be grown as a thin film on suitable garnet substrates by pulsed laser deposition ͑PLD͒, 4,6,18,[20][21][22][23][24][25][26][27][28] reactive ion-beam sputtering ͑RIBS͒ ͑Refs. 29-31͒, or other vapor deposition techniques.…”

Preparation of Bi₂Gd₁Fe₅O₁₂ magnetic garnet films showing Faraday rotation of 36.3 deg./µm on glass substrates by metal organic decomposition method

“…Among them, bismuth substituted gadolinium iron garnet (Bi:GdIG) is one of the ferrimagnetic rate-earth iron garnets showing perpendicular magnetic anisotropy [8,9]. There are several methods to prepare the Bi:GdIG thin films such as a laser ablation [10], RF magnetron sputtering [11], liquid phase epitaxy [12], etc. Metal organic decomposition (MOD) method is a promising one to prepare magnetic garnet film, because it is a simple fabrication method which is composed of spin coating of the MOD solutions ( 12 thin films have been fabricated on (111) oriented gadolinium gallium garnet (GGG) single crystal substrates [9,10,11,12,13,14,15], and glass substrates [16].…”

In order to apply Bi:GdIG or Bi:YIG thin films in Si/SiO 2 based waveguide optical isolators [17,18,19] and MOSLMs [7], it is required that Bi:GdIG thin films are prepared on glass substrates or SiO 2 thin films.…”
