We synthesized, for the first time, superconducting eutectic composed of two new superconducting phases, namely of Mo_2Re_3B_x and of Mo_3Re_2B_x (where x≈1) and investigated its basic transport, magnetic, and microwave properties. The transition temperatures T_c were equal to 6.6 K and to 8.7 K for Mo_3Re_2B_x and Mo_2Re_3B_x 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.
