“…Detailed XRD studies supported by the Rietveld analysis for all annealed samples were described in our previous studies [17,18]. They revealed coexistence of two main crystalline phases: the dominant La(Fe,Si) 13 -type (193) P. Gębara and minority α-Fe(Co,Si) phase.…”

In the present work the influence of Al and Ga on formation of La(Fe,Si)13-type phase in magnetocaloric LaFe11.14Co0.66Si1.2−xMx (where x = 0.1, 0.2, 0.3; M = Al, Ga) alloys subjected to annealing at 1323 K for 15 days was studied using the Mössbauer spectroscopy. For annealed samples, two crystalline phases were recognized: the dominant paramagnetic La(Fe,Si)13-type phase, and minor fraction of ferromagnetic α-Fe(Co,Si). It was revealed that Al improved formation of 1:13 phase in contrast to Ga, which caused reduction of the ability of formation of the expected phase.

“…The Mössbauer studies revealed paramagnetic state of the La(Fe,Si) 13 -type phase at room temperature for all the investigated specimens, which shows that the Curie temperature of this phase is lower than room temperature. Detailed Curie temperature investigations were described in our previous works [17,18].…”

Fe-based amorphous alloys were characterized by X-ray diffraction, transmission Mössbauer spectroscopy and vibrating sample magnetometry. The studies were performed on (Fe0.75B0.15Si0.1)100−xZrx (x = 0, 1, 3) metallic glasses in the form of ribbons. The glassy samples were prepared by the "melt spinning" technique in argon protective atmosphere. The XRD patterns show the broad diffraction halo that is typical for amorphous Fe-based alloys. The Mössbauer spectroscopy allows to study the local environments of the Fe atoms in the glassy state, showing the changes in the amorphous structure due to the changing of Zr addition. From hysteresis loops obtained from vibrating sample magnetometry measurements, coercive force and saturation magnetization were determined versus different Zr content. The obtained magnetic properties allow to classify the studied amorphous alloys in as-cast state as soft magnetic materials.

The paper presents a characterization of the phase structure by X-ray diffraction and isothermal magnetic entropy changes for the amorphous Fe58Co10Zr10Mo5W2B15 alloy sample in the as-quenched state. An ingot sample was obtained by arc-melting. The ribbon sample was obtained by the melt-spinning technique. The magnetic measurements at various temperatures allowed for the study of the Curie temperature TC and magnetic entropy changes |∆SM |. In order to determine the Curie temperature TC of amorphous phase, three independent methods were used. Determination of the Curie temperature TC for the amorphous alloys is not a trivial problem, as magnetization does not decreases rapidly around TC. Therefore it is essential issue to establish TC using few complementary methods. X-ray diffraction analysis revealed a fully amorphous structure of the ribbon samples.
