Itinerant electron metamagnetic transition in La(FexSi1−x)13 intermetallic compounds
TLDR
A first-order transition above the Curie temperature for ferromagnetic La(FexSi1−x)13 (x=0.86 and 0.88) compounds has been confirmed by applying a magnetic field.Abstract:
A first-order transition above the Curie temperature for ferromagnetic La(FexSi1−x)13 (x=0.86 and 0.88) compounds has been confirmed by applying a magnetic field. The magnetic state changes from the paramagnetic to the ferromagnetic state and the transition field increases with temperature, indicating an itinerant electron metamagnetic (IEM) transition. The IEM transition is broad in x=0.86 and becomes clearer in x=0.88, which takes a negative slope of the Arrott plot. The volume change just above the Curie temperature for x=0.88 is huge, about 1.5%, which is caused by a large magnetic moment induced by the IEM transition.read more

TL;DR: In this article, it was shown that it is possible to render certain paramagnetic substances ferromagnetic by the application and subsequent removal of sufficiently strong magnetic fields, and the conditions for this effect to occur are discussed and illustrated with particular reference to palladium.

Mictomagnetic, ferromagnetic, and antiferromagnetic transitions in La(FexAl1-x)13 intermetallic compounds.
TL;DR: The breakdown of long-range ferromagnetic order at high x values can be explained by modifications of the iron moment and their coupling at a large Fe-Fe coordination number, but with application of a magnetic field, the feromagnetic state can be fully recovered.
