Magnetic studies of synthetic amorphous carbon (a-C) and amorphous carbon doped with sulfur powder (a-CS) are described, showing (i) characteristic magnetic behavior and (ii) 2 reveals traces of two superconducting (SC) stages. K indicates K. (I) Examining the zero-field cooled (ZFC) twist at room temperature, its temperature dependence exhibits several elusive peaks expected to form between 50 and 80 K, but the exact The initial stage is unknown. FC bifurcation and second his ZFC deletion completely remove these vertices. As a result, the ZFC peak lies below the near-zenith FC twist (FC ZFC), a rare observed rarity. These magnetic anomalies are inherent properties of a-C and a-CS materials. (ii) SC had three different AC sources.(a) Commercial a-C powder contains 0.21% sulfur, so two different a-CS stages (33 K and 65 K) are thought to form the beginning of the two reported SC states. . The composition of these two phases is not entirely ambiguous. A strong reaction at 250 °C with additional sulfur can completely replace the minor SC component in the 33 K stage, but the integrated (a-C) powder (obtained by sucrose decomposition) is not SC . However, the a-CS powder also showed evidence of SC state at TC = 42 K when combined with sulfur in a controlled atmosphere and heated to 400 °C. (c) a-c minor videos also experience this. The film is not SC in the initial state, but after treatment with sulfur at higher temperature, the SC stage occurs at TC = 34K. This conclusively indicates that all observable SC stages are the result of different dark a-CS phases. We admit that they represent closely related high-TC curates and Fe-As-based frameworks, as both SC and magnetic states exist in a-C and a-CS powders.
