The Structure And Magnetic Properties Of Fe0.50cr0.50-Xsix (X=0-0.1) Nano Materials Prepared Via Mechanical Alloying Technique

Kontan Tarigan


The main objective of this study is the investigation of the relationship between the structure and the magnetic properties of Fe50Cr50-xSix (x=0-0.1) metastable alloys which were made by mechanical alloying for 36 hours. Research in this field feels still lacking. To understand the structure using by X-ray diffraction (XRD) and the magnetic properties are measured by using a Physical Property Measurement System (PPMS). The result with variable of x = 0-, 0.025-, 0.050-, 0.075- and 0.1 wt. %. are crystallite sizes (D) increase from 7 to 8.5 nm, the structural strains (ϵ) are down about 20% from normal circumstances. The grain sizes increase causing the number of domains to increase then the mobility of domain decreases or coercivity (Hc) decreases from 120 to 40 Oe. In amorphous state coercivity rises and crystallite sizes decrease, suddenly.
