Epitaxial Growth and Magnetic Properties of Ferromagnetic Thin Films
Summary
Epitaxial growth of ferromagnetic thin films has emerged as a cornerstone of modern spintronics and magnetoelectronic device engineering. By depositing atomically ordered layers on single-crystal substrates, researchers achieve precise control over crystalline orientation, interface quality and strain, all of which directly influence magnetic anisotropy, coercivity and Curie temperature. Materials such as Mn5Ge3, Fe3O4, CoFe2O4 and Heusler alloys have been extensively explored for their ability to integrate with group-IV semiconductors or oxide substrates, unlocking efficient spin injection, tunnelling magnetoresistance and magneto-optical effects. The interplay between lattice mismatch and misfit dislocations is mitigated through buffer layers, surfactant-mediated growth or carbon doping, yielding high-quality films with tailored magnetic easy axes. Advanced in situ characterisation techniques—reflection high-energy electron diffraction, scanning tunnelling microscopy and synchrotron X-ray diffraction—enable real-time monitoring of growth kinetics and phase evolution, while ex situ magnetic measurements such as vibrating sample magnetometry and ferromagnetic resonance elucidate anisotropy fields and damping parameters. These developments underpin applications ranging from magnetic random-access memory to spin transistors, emphasising the global significance of epitaxial ferromagnetic thin films for energy-efficient information technology and quantum sensing.
