Investigating the magnetic and magnetocaloric behaviors of LiSm(PO).

We report a detailed study on the magnetic behaviors and magnetocaloric (MC) effect of a single crystal of lithium samarium tetraphosphate, LiSm(PO). The analyses of temperature-dependent magnetization data have revealed magnetic ordering established with decreasing temperature below , where is the minimum of a d/d curve and varies as a linear function of the applied field . The Curie temperature has been extrapolated from () data, as → 0, to be about 0.

Synthesis of highly branched hollow trimetallic PdAgCu nanoparticles.

An aqueous, room temperature, and surfactant-less synthetic route based on galvanic replacement and co-reduction is reported to yield PdAgCu nanoparticles (NPs) with a high density of sharp and branched tips. The PdAgCu NPs are of high-purity, uniform size and more than 90% of them adopt branched tips. Besides, the PdAgCu NPs exhibit hollow interiors, well-alloyed nature, and a tuneable localized surface plasmon resonance peak in the near infrared region.
