Advanced applications in optics, for example, Faraday isolators, demand for complex magneto‐plasmonic nanostructures which exhibit large Faraday rotation. These structures is fabricated by a Layer‐by‐Layer approach, albeit this being a slow technique. Here, the ultrasonic spray coating as a promising alternative method toward the formation of hybrid magneto‐plasmonic structures is pioneered by the authors. Ultrasonic spray coating is a stable, fast, and tunable mass production method applied in this work to deposit gold and iron oxide nanoparticles. Altering multiple deposition parameters give the spray coating technique a large amount of control over the coverage. Optical and magneto‐optical properties, layer formation and surface coverage of single and hybrid layers with increasing thickness and number of layers are studied and compared to samples synthesized by Layer‐by‐Layer deposition. Ultrasonic spray coating paves the way to the widespread application of innovative and versatile hybrid magnetic‐plasmonic nanocomposites.
