| We synthesized, for the first time, superconducting eutectic composed of two new superconducting phases, namely of Mo2Re3Bx and of Mo3Re2Bx (where x≈1) and investigated its basic transport, magnetic, and microwave properties. The transition temperatures Tc were equal to 6.6 K and to 8.7 K for Mo3Re2Bx and Mo2Re3Bx compound, respectively. The phases present in the eutectic were identified by means of energy dispersion spectroscopy analyses. It was also shown that the two phases in the eutectic were separated by thin boron interface and formed regular network of the Josephson junctions which very effectively absorbed microwave energy. |
