Gadolinium-Iron Alloy Sputtering Targets: The Building Block of Advanced Magnetic Thin Films

Gadolinium (Gd) and iron (Fe) are two key elements in the field of magnetism. When combined into an alloy and formed into a sputtering target, the resulting Gadolinium Iron (GdFe) alloy becomes a high-performance material widely used in spintronics, magnetic memory, and sensor technologies.

🔬 What is a Gadolinium Iron Alloy Sputtering Target?

A Gadolinium Iron alloy sputtering target is a solid material composed of gadolinium and iron in a specific atomic ratio, commonly GdₓFe₍₁₋ₓ₎ where x is between 0.2 and 0.6. These targets are used in physical vapor deposition (PVD) techniques to produce thin magnetic films with controllable magnetization and anisotropy.

🧪 Key Properties:

• Composition: Typical ratios include Gd₄₀Fe₆₀, Gd₃₀Fe₇₀, or customized on request

• Purity: ≥99.9% total metal basis

• Magnetic Behavior: Ferrimagnetic with tunable Curie temperature

• Structure: Amorphous or nanocrystalline films depending on deposition conditions

• Coercivity: Adjustable via Gd:Fe ratio and thermal treatment

🛠️ Applications:

1. Spintronics
   GdFe targets are widely used to deposit spintronic materials, which exploit electron spin rather than just charge, enabling next-generation memory and logic devices.

2. Magneto-Optical Recording
   GdFe films offer excellent magneto-optic Kerr effect (MOKE), making them ideal for optical data storage systems.

3. Magnetic Sensors
   Thin films derived from GdFe sputtering targets are applied in high-sensitivity magnetic field detection for industrial and automotive sensors.

4. Memory Devices
   Used in MRAM (Magnetoresistive Random Access Memory) and similar non-volatile memory technologies due to their fast switching speed and scalability.

5. Temperature-Sensitive Magnetic Devices
   With a tunable Curie temperature, GdFe is ideal for thermal-triggered magnetic control and magnetocaloric effects.
