Effect of Low Substrate Temperature on the Magnetic Properties and Domain Structure of Fe₇₀Ga₃₀ Thin Films
We report on the effect of low substrate temperature on the correlation between structure, magnetic properties, and micromagnetic behavior of Fe 70 Ga 30 thin films. The enhanced grain size and the decrease in the number of pinning centers are in correlation with the enhanced saturation magnetizatio...

| description | We report on the effect of low substrate temperature on the correlation between structure, magnetic properties, and micromagnetic behavior of Fe 70 Ga 30 thin films. The enhanced grain size and the decrease in the number of pinning centers are in correlation with the enhanced saturation magnetization and domain size (~0.2- 0.5~\mu \text{m} ), respectively. Estimated effective magnetic anisotropy energy ( K_{\mathrm {eff}} ) is found to increase with substrate temperature from 7.5 \times 10^{5} J/m 3 (room temperature) to 13.6 \times 10^{5} J/m 3 (350 °C). The coercivity variation from the object-oriented micromagnetic framework (OOMMF) simulation is in line with respect to experimental values. Spin structure from simulation also indicates multiple-domain configuration when there is a magnetization reversal. |
