Quantum spin liquid (QSL) is a novel state of matter with exotic excitationsand was theoretically predicted to be realized most possibly in an S=1/2 kagomeantiferromagnet. Experimentally searching for the candidate materials is a bigchallenge in condensed matter physics and only two such candidates werereported so far. Here we report the successful synthesis of a new spin-1/2kagome antiferromagnet ZnCu3(OH)6SO4. No magnetic ordering is observed down to50 mK, despite a moderately high Weiss temperature of {\theta}W ~ -79 K. Itstrongly suggests that the material is a new QSL candidate. Most interestingly,the magnetic specific heat clearly exhibits linear behaviors in twolow-temperature regions. Both behaviors exactly correspond to twotemperature-independent susceptibilities. These consistently reveal a novelre-entrance phenomenon of gapless QSL state at the lowest temperatures. Thefindings provide new insights into QSL ground and excited states and willinspire new theoretical and experimental studies.
