This paper explains the effect of structural behaviour and electrical properties of cubic NaZn13-type La(FeSi)13 compounds annealed at different high temperatures from 1000ºC to 1200ºC. The Raman spectroscopy measurement revealed a different level of coexistence of La(FeSi)13-type phase and α-Fe in 1000ºC, 1100ºC and 1200ºC annealed samples. The different level coexistence of the phases suggested that the samples show a significant phase change with different annealing temperature. This fi...

Since the discovery of magnetocaloric effect (MCE), numbers of method in producing magnetocaloric materials has been studied. Among those methods, ball milling has been shown as a very versatile technique with several advantages compared to other preparation methods. In this work, the effect of ball milling preparation technique on the phase structural behaviour and electrical properties of MnCoGe alloys has been analysed. The changes in the structural behaviour have been studied by X-ray powder...
