Abstract

Cubic NaZn13-type compounds of the form La(FexAl 1-x)13 was stabilised with compositions between LaFe 6Al7. For compositions above LaFe11.2Al 1.8 (x=0.861) a low-temperature antiferromagnetic state is present in small external fields. However, upon increasing the field to a few tesla, an exceedingly sharp spin-flip transition with remarkably large hysteresis occurs to the fully saturated ferromagnetic state. The origins of this unusual metamagnetic transition are discussed in terms of the special crystal structure.
