Low-dimensional materials with broken inversion symmetry and strongspin-orbit coupling can give rise to fascinating quantum phases and phasetransitions. Here we report coexistence of superconductivity and ferromagnetismbelow 2.5\,K in the quasi-one dimensional crystals of non-centrosymmetric(TaSe$_4$)$_3$I (space group: $P\bar{4}2_1c$). The unique phase is a directconsequence of inversion symmetry breaking as the same material also stabilizesin a centro-symmetric structure (space group: $P4/mnc$) where it behaves like anon-magnetic insulator. The coexistence here upfront contradicts the popularbelief that superconductivity and ferromagnetism are two apparentlyantagonistic phenomena. Notably, here, for the first time, we have clearlydetected Meissner effect in the superconducting state despite the coexistingferromagnetic order. The coexistence of superconductivity and ferromagnetismprojects non-centrosymmetric (TaSe$_4$)$_3$I as a host for complex groundstates of quantum matter including possible unconventional superconductivitywith elusive spin-triplet pairing.
