Heating rate dependence of coercivity and microstructure of Fe–B–P–Cu nanocrystalline soft magnetic materials
2021, Journal of Alloys and CompoundsCitation Excerpt :There is no difference between the activation energies in the primary crystallization process of the P-rich and B-rich alloys (∼139 kJ/mol), regardless of the large difference in the heating rate dependence of Hc and dave. In literature, the activation energies for the diffusion of P in α-Fe and an amorphous phase were reported to be 178 kJ/mol and 169 kJ/mol [20,21]; hence the activation energy for the crystallization of α-Fe estimated in this work is slightly lower than the activation energy for the diffusion of P. However, it is not easy to determine the rate-controlling steps only from the thermal analysis. As the first step for determining the rate-controlling steps, we investigated the elemental distribution in the samples after the primary crystallization process using APT.
Characterization of ultra-thin nickel-silicide films synthesized using the solid state reaction of Ni with an underlying Si:P substrate (P: 0.7 to 4.0%)
2016, Microelectronic EngineeringCitation Excerpt :Phosphorus being light and highly mobile (compared to Ni or Si) segregates to form new compounds with Ni starting 500 °C. The fact that the GIXRD profiles (for NixPy compounds) remaining the same (500–875 °C), indicates the attainment of maximum solubility of P in Ni [41–44]. Furthermore, comparing the GIXRD after RTP (Fig. 3) and post RTP anneals (Fig. 8), it can be noticed that, though NiSi being the sole phase obtained until 500 °C RTP, the films formed at 350 °C (0.7% P) and 400 °C RTP(2.0–4.0% P), when subjected to post RTP anneal at 500 °C, it is not stable and leads to phase decomposition.
