Structural and Mössbauer studies on mechanical milled SmCo5/α-Fe nanocomposite magnetic powders

A structural investigation of SmCo5/Fe nanostructured alloys obtained by high-energy ball milling and subsequent annealing

“…However, our previous Mössbauer investigations suggested that Fe/Co interdiffusion occur during the process [11]. Since then, this result has been confirmed by other authors [25][26][27]. In the present study, we proceed to a systematic study of the microstructure of SmCo 5 /α-Fe alloys by Mössbauer spectrometry with the aim to follow accurately the evolution of the Fe-containing phases upon milling and subsequent annealing.…”

One-pot synthesis of a chitosan-based hydrogel as a potential device for magnetic biomaterial

“…This paramagnetic doublet implies that the iron atoms exhibit a fast electronspin relaxation rate. The values of relative intensities for the CS-co-AAc magnetic hydrogel with average particle sizes of 300 mm could not be observed, according to results determined by Saravanan [18]. They show that the relative intensity determined CSÀcoÀAAc magnetic hydrogel with particle size ranging from 300 to 425 mm.…”

Effect of sintering temperature on the structure and magnetic properties of SmCo5/Fe nanocomposite magnets prepared by spark plasma sintering

“…The bright phase was found to have a composition close to the Sm 2 Co 17 phase and to contain about 7 at% Fe. The partial Fe substitution for Co in the SmCo 5 and Sm 2 Co 17 phases was attributed to the inter-diffusion of Fe and Co during milling [23,24]. At higher sintering temperatures, one can notice that the SmCo 5 matrix consists of uniform distribution of bright phase (Sm-rich) along with the increasing proportion of black phase (Fe(Co)).…”
