The Lanthanum Calcium Manganese Oxide Target (LCMO) features a perovskite crystal structure, commonly represented by the formula La₁₋ₓCaₓMnO₃. In this structure, calcium partially replaces lanthanum, allowing precise adjustment of the material’s electronic and magnetic characteristics. LCMO is distinguished by its colossal magnetoresistance (CMR), a property where its electrical resistance undergoes significant changes when subjected to a magnetic field. This material exhibits strong interactions among its spin, charge, and lattice components, resulting in intricate phase transitions and highly adjustable conductivity. Additionally, LCMO displays ferromagnetic behavior at specific doping levels and temperatures, with its Curie temperature varying based on calcium concentration. Its thermal stability and uniform chemical composition make it ideal for high-temperature deposition techniques such as pulsed laser deposition (PLD) and RF magnetron sputtering. These attributes position LCMO as a leading material for both experimental and industrial applications that demand precise manipulation of magnetic and transport properties in thin films.

Lanthanum is a soft, silvery-white, ductile metal classified among the rare earth elements. It is typically extracted from minerals such as monazite and bastnäsite. Renowned for its high melting point and excellent electrical conductivity, lanthanum forms stable oxide compounds. Common applications include catalysts, phosphors, and battery technologies like Nickel-Metal Hydride (NiMH) batteries. Additionally, lanthanum oxide is pivotal for high-temperature applications and solid oxide fuel cells (SOFCs), where it enhances device performance and stability.
Calcium is a silvery-white, moderately hard alkaline earth metal with an atomic number of 20 and an atomic weight of approximately 40.08. Highly reactive, especially with water and oxygen, calcium forms a protective oxide and hydroxide layer that prevents further corrosion. Essential in biological systems as a primary component of bones and teeth, calcium is also used in materials science as a reducing agent for metals like uranium and thorium. In thin film and ceramic applications, calcium aids in forming complex oxides with unique electrical and magnetic properties, such as in perovskite materials like LCMO (La₁₋ₓCaₓMnO₃).
Manganese is a transition metal with the atomic number 25, located in Group 7 of the periodic table. It is a hard, brittle, silver-gray metal that does not occur freely in nature but is found in minerals like pyrolusite (MnO₂). Manganese is vital for steel production, enhancing hardness, stiffness, and strength. It is also extensively used in battery manufacturing, ceramics, fertilizers, and electronic materials. In advanced materials and thin films, manganese is a key component in magnetic and oxide compounds such as Lanthanum Strontium Manganite (LSMO), which is utilized in spintronics, magnetic sensors, and memory devices due to its colossal magnetoresistance and other functional properties.
