“…Depending on deposition conditions, LFMR might be missing in SFMO thin films deposited by PLD onto SrTiO 3 (001) substrates . However, the tunneling barriers necessary for LFMR could be additionally created, for instance, by a postdeposition film annealing at 475–500 °C in an ultrapure Ar (99.9995%) atmosphere for 5 h or by annealing in a reducing 5% H 2 /N 2 atmosphere for 10 h . Contrarily, neither magnetic nor magnetotransport or structural properties were improved by postdeposition annealing of SFMO thin films between 500 and 1100 °C in vacuum, Ar, 5% H 2 /Ar, and air atmospheres for 5 or 10 h .…”

This work reviews some fundamental issues that are relevant for the fabrication of stable‐phase strontium ferromolybdate thin films. The main challenges for strontium ferromolybdate thin film deposition arise from the sensitivity of the material's magnetic properties to point defect formation: i) Antisite defect formation and oxygen nonstoichiometry should be avoided by precise composition control during film manufacturing; ii) a highly ordered state of the correct phase and B‐site cation valence will be obtained only in a very narrow window of growth conditions; iii) to avoid additional antisite disorder with decreasing synthesis temperature, the effective temperature at the film surface should be increased by an energy flux to the growing film surface. Since thin film deposition is nonequilibrium in nature, the review starts with the consideration of equilibrium phase stability. Cation and oxygen stoichiometries are analyzed with regard to their effect on key magnetic properties. Film strain formed due to thermal and lattice mismatch is of great concern since it influences the choice of the substrate. Finally, thin film deposition techniques are valued for their benefits in strontium ferromolybdate thin film technology.

“…The most used and optimized method for the growth of SFMO thin film is pulsed laser deposition (PLD) [57][58][59][60][61][62][63][64][65][66][67][68][69][70][71], however due to inherent complexity of SFMO, its growth as a thin film, has proven to be an arduous task. A brief look through the vast array of SFMO thin film literature reveals that the growth conditions are still in need of perfection [72][73][74][75][76][77][78][79][80][81][82][83]. The substrate temperature, vacuum, oxygen partial pressure, and gas atmosphere vary from one reference to the next, making it difficult to ascertain the optimal set of growth conditions for SFMO thin films.…”

The family of double perovskites first received attention in the 1960s, but the discovery of low field magnetoresistnace (LFMR) and half metallicity of the Sr 2 FeMoO 6 (SFMO) compound was made by Kobayashi et al. in 1998. A fully spin polarized half-metal SFMO (T c > 400) with excellent magnetoresistance response relatively at small applied fields and high temperatures makes SFMO an ideal candidate for room temperature spintronics applications. Primarily, most of the research work on double perovskites SFMO has been focused on bulk ceramic samples and aimed to understand their structural, magnetic, and magnetotransport properties, along with correlation among them. A material such as SFMO that exhibits a large decrease in resistivity and magnetically order well above room temperature is necessary for the advancement of spintronic devices. If the bulk properties observed could be reproduced in thin films, industrially produced SFMO-based spintronic devices could become a reality. Therefore, the purpose of this chapter is to present the detailed background and descriptions of the double perovskite Sr 2 FeMoO 6 (SFMO) thin films and heterostructures with main emphasis to improve or achieve room temperature magnetoresistance properties especially for room temperature magnetoresistive device applications.
