Growth and characterization of epitaxial magnesium ferrite thin films

Abstract

Epitaxial magnesium ferrite thin films have been grown by molecular beam epitaxy (MBE) on MgO(100). Growth conditions such as substrate temperature and growth rates were optimized. By using different characterization techniques, structural, electrical and optical properties of the films were studied as a function of Mg content. In particular, we highlight the importance of the growth rate on the actual Mg/Fe ratio in the film.

Formation of ultrathin cobalt ferrite films by interdiffusion ofFe3O4/CoObilayers

“…For most studies, thin ferrite films are prepared by sputter deposition [11,19], pulsed laser deposition [20], molecular beam epitaxy [21], or chemical solution deposition [22]. Here, we investigate an alternate pathway to form CoFe 2 O 4 thin films by depositing a Fe 3 O 4 /CoO bilayer stack on Nb:SrTiO 3 (001) using reactive molecular beam epitaxy.…”

Low-temperature in situ preparation of Eu3+/Tb3+-doped CaMoO4/SrMoO4 nanoparticle thin films and their application in anti-counterfeiting

“…Consequently, they present an efficient, dependable, and innovative solution for addressing the challenges in the field of anti-counterfeiting. Traditional approaches for producing luminescent thin films involve sputter deposition, [18][19][20][21][22][23] molecular beam epitaxy, [24][25][26][27] chemical vapor deposition, [28][29][30][31][32] and self-assembly techniques. [33][34][35] Although the synthesis of luminescent films has been well developed, it is still a great challenge for low-temperature preparation of highly luminescent films that can be printed with customized patterns.…”
