| Abstract Scope |
Superconducting high-entropy alloys (HEA) are the new category of disordered superconductors. These materials exhibit excellent mechanical properties, great stability in extreme temperature, and significant robustness to high pressure. Such properties make them a perfect candidate for high-field magnets in LHC, ITER, or NMR applications. In this work, we present superconducting properties of two HEA powders: Nb34Ti33Zr14Ta11Hf8 and Ti0.5(ZrNbTaHf)0.5 obtained in ultrasonic atomization process. The alloys were prepared by arc melting of the pure elements in a homogeneous sphere, then, they were refined into highly spherical, micrometer sized particles using ultrasonic powder atomizer. Homogeneity of samples was examined using scanning electron microscopy. Physical and magnetic properties of the systems were characterized by means of X-ray powder diffraction, AC magnetic susceptibility, DC magnetization, and specific heat measurements. Experimental data revealed that both alloys crystallize in body-centered cubic structure and exhibit type-II superconductivity at low temperatures. |
