Magnetic Phase Transition in Spark-Produced Ternary LaFeSi Nanoalloys
Using the magnetocaloric
effect in nanoparticles holds great potential
for efficient refrigeration and energy conversion. The most promising
candidate materials for tailoring the Curie temperature to room temperature
are rare-earth-based magnetic nanoalloys. However, only few high-nuclearity
lanthanide/transition-metal nanoalloys have been produced so far.
Here we report, for the first time, the observation of magnetic response
in spark-produced LaFeSi nanoalloys. The results suggest that these
nanoalloys can be used to exploit the magnetocaloric effect near room
temperature; such a finding can lead to the creation of unique multicomponent
materials for energy conversion, thus helping toward the realization
of a sustainable energy economy
