Discontinued (Discontinued) ST6550 Samarium Planar Target

Samarium Planar Target Description

Stanford Advanced Materials (SAM) specialises in the manufacture of high-quality Samarium (Sm) planar sputtering targets that utilise the exceptional magnetic properties, thermal stability, and oxidation resistance of this element. As a rare earth metal with a melting point of 1 072 °C, Samarium naturally forms a self-protecting oxide layer, which ensures long operational reliability during thin film deposition processes. The carefully engineered, fine-grained microstructure of the targets guarantees consistent sputtering performance and enables highly controlled and repeatable film formation.

The Samarium targets produced by SAM under strict quality assurance protocols are customisable in purity levels (99.9%-99.99%) and dimensions to meet specific coating specifications. Their inherent material advantages – including robust interfacial adhesion and corrosion resistance – make them ideal for advanced applications requiring wear-resistant or magneto-optical coatings. SAM's decades of experience in rare earth metallurgy ensure that these targets undergo precision optimisation, providing industry-leading deposition uniformity and process yield for research, semiconductor, and industrial coating systems. Technical support and customised configurations are available to address complex challenges in thin film technology.

Samarium Planar Target Applications

1. Magnetic Thin Films and Magneto-Optical Storage:

Used in magneto-optical discs (MO discs) for high-density data storage and optical isolators, exploiting the strong magneto-optical effects of Sm (e.g., Faraday rotation).

Applied in spintronic devices such as magnetic tunnel junctions (MTJs) and magnetoresistive RAM (MRAM) for high-performance computing and energy-efficient storage.

2. Semiconductors and Microelectronics:

Deployed as Sm-based thin films in Hall sensors and magnetoresistive devices to enhance magnetic field sensitivity.

Function as diffusion barriers or functional coatings in integrated circuits, improving high-temperature stability and oxidation resistance.

3. Optical Coatings:

For optical components in the infrared range (e.g., laser mirrors, IR windows) due to the low absorption of Sm at IR wavelengths.

Forms anti-reflective multilayer coatings to optimise light transmittance and durability in precision optics.

4. Wear-Resistant and Protective Coatings:

Applied to aerospace components (e.g., turbine blades) and industrial tools to enhance corrosion resistance, high-temperature oxidation resistance, and hardness.

5. Research & Emerging Technologies:

Enables the deposition of Sm compound thin films (e.g., SmFeAsO) for studies on high-temperature superconductivity.

Used in neutron-absorbing coatings or surface modifications for materials in nuclear reactors.

Frequently Asked Questions about Samarium Planar Targets

Q1: Can custom dimensions or shapes be ordered?

A1: Yes. We support customisation of diameter (50-200 mm), thickness (3-10 mm), and bonding configurations (e.g., Cu/Ag backing plates). Please send us your specifications for rapid prototyping.

Q2: What is the typical lifespan of a Samarium target?

A2: Lifespan depends on sputtering parameters (power, gas pressure), but our fine-grained microstructure (<50 µm grain size) ensures material utilisation of >85% under standard DC/RF sputtering conditions.

Q3: How should Samarium targets be stored and handled?

A3: Store in a dry inert gas environment (Ar/N₂) to avoid surface oxidation. Use gloves when handling to prevent contamination. Cleaning protocols prior to sputtering are recommended.

Related Information

1. Raw Materials - Samarium

Samarium (Sm) is a rare earth metal with atomic number 62 and an atomic weight of 150.36. It is a silvery-white metal that is moderately hard and brittle, with a melting point of 1 072 °C (1 962 °F). Samarium readily reacts with oxygen, forming an oxide layer that protects it from further corrosion. Although Samarium is classified as a rare earth, it is relatively abundant and is primarily extracted from minerals such as monazite and bastnäsite.

Samarium is primarily known for its strong magnetic properties, making it a key component in high-performance magnets, particularly Samarium-Cobalt permanent magnets (SmCo), valued for their high thermal stability and resistance to demagnetisation. Due to its ability to absorb infrared radiation and enhance material properties, it also plays a significant role in optical and electronic applications. Furthermore, Samarium compounds are utilised in specialised ceramics, glass manufacturing, and nuclear applications due to their neutron absorption capability. With its unique combination of magnetic strength, thermal stability, and chemical resistance, Samarium is a critical element in high technology and materials science.
