“…Moreover, it has been observed that in ultrathin garnet films the easy magnetization axis can be out-of-plane due to the anisotropies interplay. 12,22,28 Overall, the saturation magnetization for three BIG series show the same behavior as the Faraday rotation: the decrease with decreasing film thickness and 4pM S (BIG/SGGG) > 4pM S (BIG/GGG) > 4pM S (BIG/YAG) for t < 50 nm. The magnetic and magneto-optic properties depend clearly on strain.…”

Thin film properties are strongly influenced by strain and low dimensionality effects, especially when the film thickness is about a few unit cells, which corresponds to the thicknesses targeted in most of contemporary studies. In oxides, these effects are responsible for the dramatic modification of the physical properties that sometimes can change the nature of a material. Nevertheless, it is not always possible to distinguish the contribution of the strain to the changes in physical properties from the contribution due to low dimensional effects. In the present study, bismuth iron garnet Bi3Fe5O12 (BIG) is chosen to separate both effects. This material possesses, among other outstanding physical properties, the giant Faraday rotation that allows investigating films with the thickness below a few unit cells. Three series of BIG films of various thicknesses were grown on three isostructural substrates with different lattice parameters: Y3Al5O12(001), Gd3Ga5O12(001), and (GdCa)3(GaMgZr)5O12(001). The structural, magnetic, and magneto-optic properties were studied as a function of film thickness and strain. Furthermore, critical behavior of the BIG films was investigated in the vicinity of the Curie temperature. The obtained results allowed distinguishing between the low dimensional effects and the strain due to the epitaxial growth. While the size reduction is mostly responsible for the decrease of the magnetic characteristics of the films, the strain influences rather the critical thickness below which the material starts to behave as a low dimensional system.

“…The modification of the magnetic characteristics is observed as well in oxide thin films 5 and is often inaccurately ascribed to the influence of the epitaxial strain. 6,[12][13][14] Therefore, it is crucial to be able to separate the strain effects from those originating from the reduction of the material thickness.…”

“…Rare-earth iron garnets (REIG) with PMA have also been developed, in which the PMA originates from magnetoelastic anisotropy due to the epitaxial mismatch strain of the REIG on the gadolinium iron garnet (GGG) substrate [12,18]. TmIG [5,18,19], SmIG (Sm 3 Fe 5 O 12 ) [20], and TbIG (Tb 3 Fe 5 O 12 ) [21] films, as well as Ce-or Bi-substituted YIG [22][23][24], exhibit strain-induced PMA. Other thin film RE garnets include GdIG (Gd 3 Fe 5 O 12 ) [25] and LuIG (Lu 3 Fe 5 O 12 ) [26] with in plane easy axis.…”

“…The epitaxial strain can be induced in case where the thickness is thinner than the critical thickness. The critical thickness of SmIG and LuIG are 660 and 1250 Å, respectively, calculated by the equation shown in [10]. The thicknesses of the both films are 100 Å.…”

Garnet-type ferrite thin films of Sm 3 Fe 5 O 12 and Lu 3 Fe 5 O 12 have been grown on (0 0 1)-oriented Gd 3 Ga 5 O 12 substrates by a pulsed laser deposition. An electric-fields-induced spin wave can be excited in the strained Sm 3 Fe 5 O 12 films at room temperature using sub-picosecond pulsed wave. On the other hand, it is not observed in the strained Lu 3 Fe 5 O 12 films, due to the anisotropic crystal elongation based on the epitaxial strain.
