DESCRIPTION:High-entropy compounds\, stabilized by configurational entropy
 \, have attracted considerable attention due to their unique properties an
 d functionalities [1-3]. In this study\, we applied the high-entropy conce
 pt to antimonide systems and discovered an entropy-stabilized antimonide c
 ompound with a NiAs-type structure [4]. Specifically\, we investigated the
  superconducting properties of (RuRhPdIr)₁₋ₓPtₓSb and found that t
 he superconducting transition temperature (Tc) and upper critical field (H
 c₂) exhibit strong composition dependence [5]. A maximum Tc of 3.1 K and
  a significant enhancement in Hc₂ were observed at intermediate composit
 ions\, indicating a novel "cocktail effect" arising from chemical disorder
 . These results demonstrate the potential of entropy engineering in design
 ing new superconducting materials.\n\n \n\n[1] J. W. Yeh et al.\, Adv Eng
