Iron-Nickel (Fe-Ni) Sputtering Target — Magnetic Thin-Film Research
High-purity iron-nickel alloy (Fe-Ni) sputtering target for deposition of permalloy (Ni₈₀Fe₂₀) and related soft magnetic thin films used in spintronics, MRAM, magnetic sensor, and magnetoresistance research. The composition is critical — slight deviation from Ni₈₀Fe₂₀ significantly affects magnetic properties.
