- Opis:
- Magnetization measurements on zero field cooled (M$\text{}_{ZFC}$) and field cooled (M$\text{}_{FC}$) with temperature T were made on Fe$\text{}_{0.7-x}$M$\text{}_{x}$Al$\text{}_{0.30}$ alloys (where M = Co or M = V). Compared to Co and V free alloy Fe$\text{}_{0.7}$Al$\text{}_{0.30}$, our results revealed that an addition of small amount of M = Co with 0≤ x≤0.10 shows linear decrease in the transition temperature T$\text{}_{f}$ as x increases. Addition of small amount of M = V with 0≤ x≤0.1 shows gradual decrease in T$\text{}_{f}$ with increasing x. The relative changes in T$\text{}_{f}$ show that an addition of V atoms is of more significance than addition of Co atoms. There is a twofold decrease which could be attributed to the ferromagnetic nature of Co atoms and to the random fields.
