Downscaling Effect on the Superconductivity of Pd3Bi2X2 (X = S or Se) Nanoparticles Prepared by Microwave-Assisted Polyol Synthesis
Abstract
<p>Pd<sub>3</sub>Bi<sub>2</sub>S<sub>2</sub> and Pd<sub>3</sub>Bi<sub>2</sub>Se<sub>2</sub> have been successfully prepared in the form of nanoparticles with diameters of ∼50 nm by microwave-assisted modified polyol synthesis at low temperatures. The composition and morphology of the samples have been studied by means of powder X-ray diffraction as well as electron microscopy methods, including X-ray intensity mapping on the nanoscale. Superconducting properties of the as-prepared samples have been characterized by electrical resistivity measurements down to low temperatures (∼0.2 K). Deviations from the bulk metallic behavior originating from the submicrometer nature of the samples were registered for both phases. A significant critical-field enhancement up to 1.4 T, i.e., 4 times higher than the value of the bulk material, has been revealed for Pd<sub>3</sub>Bi<sub>2</sub>Se<sub>2</sub>. At the same time, the critical temperature is suppressed to 0.7 K from the bulk value of ∼1 K. A superconducting transition at 0.4 K has been observed in nanocrystalline Pd<sub>3</sub>Bi<sub>2</sub>S<sub>2</sub>. Here, a zero-temperature upper critical field of ∼0.5 T has been estimated. Further, spark plasma-sintered Pd<sub>3</sub>Bi<sub>2</sub>S<sub>2</sub> and Pd<sub>3</sub>Bi<sub>2</sub>Se<sub>2</sub> samples have been investigated. Their superconducting properties are found to lie between those of the bulk and nanosized samples.</p>
