ST6605 Lanthanum Calcium Manganese Oxide Target (LCMO)

Lanthanum-Calcium-Manganese-Oxide Target (LCMO) Description

Lanthanum-Calcium-Manganese-Oxide Targets (LCMO) exhibit a perovskite crystal structure with the formula La₁₋ₓCaₓMnO₃, where calcium partially replaces lanthanum to optimise the electronic and magnetic properties of the material. It is recognised for its colossal magnetoresistance (CMR), where its electrical resistance dramatically changes in response to an applied magnetic field. This target material displays strong coupling between its spin, charge, and lattice degrees of freedom, leading to complex phase transitions and highly tunable conductivity. LCMO also shows ferromagnetic behaviour at specific doping levels and temperatures, with the Curie temperature depending on the calcium content. Due to its thermal stability and chemical homogeneity, it is suitable for high-temperature coating processes such as pulsed laser deposition (PLD) and RF magnetron sputtering. These properties make LCMO a preferred choice for experimental and industrial applications requiring precise control over magnetic and transport phenomena in thin films.

Related Information

• Raw Materials - Lanthanum (La)

Lanthanum (La) is a soft, silvery-white, ductile metal that belongs to the rare earth elements in the periodic table. It commonly occurs in minerals such as monazite and bastnäsite. Lanthanum is known for its high melting point, good electrical conductivity, and ability to form stable oxide compounds. It is frequently used in catalysts, phosphors, and battery technologies (e.g., in NiMH batteries). Additionally, lanthanum oxide is a critical material for high-temperature applications and solid oxide fuel cells (SOFC), where it enhances the performance and stability of devices.

Raw Materials - Calcium (Ca)

Calcium (Ca) is a silvery-white, moderately hard alkaline earth metal with atomic number 20 and an atomic weight of approximately 40.08. It is highly reactive, especially with water and oxygen, and forms a dull oxide and hydroxide layer that protects the metal from further corrosion. Calcium is essential in biology, as it is a major component of bones and teeth, and in materials science, it is used as a reducing agent in the production of metals such as uranium and thorium. In thin film and ceramic applications, calcium contributes to the formation of complex oxides with unique electrical or magnetic properties, such as in perovskite materials like LCMO (La₁₋ₓCaₓMnO₃).

Raw Materials - Manganese (Mn)

Manganese is a transition metal with atomic number 25, located in group 7 of the periodic table. It is a hard, brittle, silvery-grey metal that does not occur naturally as a free element but is found in minerals such as pyrolusite (MnO₂). Manganese is essential for steel production, as it increases hardness, rigidity, and strength. It is also widely used in the manufacture of batteries, ceramics, fertilisers, and electronic materials.

In the field of advanced materials and thin films, manganese is a key component in magnetic and oxide compounds such as lanthanum-strontium-manganite (LSMO), which is employed in spintronics, magnetic sensors, and storage devices due to its colossal magnetoresistance and other functional properties.
