The Lanthanum Strontium Manganite (LSMO) Target is a sophisticated perovskite oxide with the chemical formula La₁₋ₓSrₓMnO₃. By substituting Sr²⁺ for La³⁺, mixed valency is introduced in manganese ions (Mn³⁺/Mn⁴⁺), resulting in exceptional electronic and magnetic characteristics. LSMO boasts a well-ordered crystalline structure, typically achieved through solid-state reactions or sol-gel techniques, followed by high-temperature sintering to ensure phase purity and density. At optimal doping levels (usually x ≈ 0.3), LSMO exhibits metallic conductivity with low resistivity ranging from 10⁻³ to 10⁻² Ω·cm. Its notable colossal magnetoresistance (CMR) effect, where electrical resistance drastically drops in a magnetic field, makes it invaluable for room-temperature spintronic devices. Additionally, LSMO offers high thermal stability, chemical resistance in standard deposition environments, and excellent adhesion to oxide substrates like SrTiO₃ and LaAlO₃. With a density of approximately 6.3–6.5 g/cm³ and a thermal expansion coefficient between 10–12 × 10⁻⁶/K, it is compatible with various thin-film deposition methods, including pulsed laser deposition (PLD), RF sputtering, and molecular beam epitaxy (MBE). Its infrared transparency and high dielectric properties further enhance its utility in multifunctional oxide devices.
