Material Background and Characteristics

Material system: Fe ₂ ₅Co₂. ₅ GeTe ₂ belongs to the iron germanium tellurium (Fe Ge Te) system and is a derivative obtained by doping the parent material Fe ₅ GeTe ₂ with Co element substitution.

Magnetic characteristics: Relevant studies have shown that Co doping can enhance the magnetic properties of Fe ∝ Co ₂. In similar components such as ₅ GeTe ₂, antiferromagnetic ordering above room temperature is achieved (Néel temperature can reach 361 K), and there exists a mixed magnetic state of intra-layer ferromagnetism and interlayer antiferromagnetic coexistence.

Application direction: This type of material is considered an ideal platform for high-temperature antiferromagnetic spintronics and can be used to prepare devices such as magnetic tunnel junctions and spin valves.

Description of Fe2.5Co2.5GeTe2 at% 2N5 Target

Our 2N5 Fe₂.₅Co₂.₅GeTe₂ at% sputter target addresses tough challenges for van‑der‑Waals magnetic material research. Volatile tellurium easily escapes during deposition, while poor bulk homogeneity brings unwanted stoichiometry shifts, ruining your 2D magnetic thin‑film samples. We apply specialised synthesis procedures to stabilise this multi‑element alloy and lock in the precise atomic ratio across the whole target body. Carefully controlled manufacturing lowers unintended impurity content and mitigates element segregation. It enables you to achieve more consistent film composition, which is critical for trustworthy magnetic‑property measurements in lab‑scale PVD trials. Each unit goes through strict compositional checks before shipment. Standard dimensions are available, and backing‑plate bonding can be provided for simple chamber fitting. Custom geometries are supported for non‑standard experimental setups. Avoid repeated failed runs caused by stoichiometry drift; use this target to cut experimental waste and keep your 2D magnetism research moving forward.

⚠️  Purchase Precautions

Confirm specific requirements: Fe ₂ ₅Co₂. The ₅ GeTe ₂ target material is a customized product, and it is necessary to clarify the atomic ratio, purity, size (diameter x thickness), and backplate material with the supplier.

Pay attention to process details: Target materials containing Ge and Te elements have high requirements for sintering and processing technology. It is recommended to choose suppliers with mature experience in alloy target materials.

Acceptance criteria: It is recommended to provide a composition analysis report (ICP-OES or EDS) and density and size detection data upon delivery. ‌‌
