In the present work, phase constitution and thermomagnetic properties of LaFe11.14Co0.66Si1.2−xAlx (where x = 0.1, 0.2, 0.3) alloys were investigated. Ingot samples were obtained by arc-melting under the low pressure of Ar atmosphere. Subsequently samples were annealed at 1323 K for 15 days. X-ray diraction of all samples revealed coexistence of two crystalline phases dominant La(Fe,Si)13-type and minor bcc α-Fe. Furthermore, the magnetic measurements at various temperatures allowed to study the Curie temperature, magnetic entropy changes and relative cooling power.
In the present work, the phase constitution and magnetic properties of the LaFe11.14Co0.66Si1.2−xGax (where x = 0.1, 0.2, 0.3) alloys, were investigated. It was revealed that increase of Ga content in the alloy composition causes the rise of lattice parameter of the La(Fe,Si)13-type phase, which causes increase of the Curie temperature. However, the increase of Ga addition leads to decrease of magnetocaloric eect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
