Structural and Phase Transition Temperature Study of Some Iron Rich Soft Ferromagnetic Materials

Abstract

There are huge varieties of soft magnetic alloys having widespread applications in variety aspects of science and technology. However, in this paper we will discuss the X-Ray diffraction pattern of the samples FINEMET (Fe73.5Nb3Cu1Si13.5B9), SAMPLE-1 (Fe81B12Mo7), SAMPLE-2 (Fe80B12Mo7Cu1), SAMPLE-3(Fe82B12Mo7Cu1) & SAMPLE-4(Fe83B12Mo5). The peak intensity (~ 0.16 a.u.) for the amorphous metal is extremely small compared to that for a crystalline substance where the peak intensity ranges up to some thousand a.u. The XRD pattern resembles that the samples are fully amorphous material. We have also Study of the paramagnetic transition temperature of the S1(Fe81B12Mo7), S2(Fe80B12Mo7Cu1), samples. These samples are magnetically soft materials.
