Structural, Optical, and Magnetic Properties of Strontium-Doped Lanthanum Manganite Nanocrystals Studied Across Temperatures
This research investigates the temperature-dependent structural evolution, alongside the optical Raman and magnetic properties, of strontium (Sr)-doped lanthanum manganite (LaMnO3) nanocrystalline systems. The study focuses on how changes in temperature influence the fundamental characteristics of these materials. Specifically, it examines the interplay between structural phase transitions and the resulting optical and magnetic behaviors observed in the doped nanocrystals. The findings aim to provide a deeper understanding of the material's response to thermal variations. This knowledge is crucial for potential applications where LaMnO3-based materials are utilized under fluctuating temperature conditions. The research systematically analyzes the spectroscopic and magnetic signatures as a function of temperature, correlating them with observed structural modifications. The goal is to elucidate the underlying mechanisms governing these properties in Sr-doped LaMnO3.
