 trong></p> <p>The quantum kagome antiferromagnet is a good playground for 
 searching for quantum many-body states. Not only zero-field spin liquids\,
  but also magnon crystallization with 7/9\, 5/9\, and ⅓ magnetization an
 d field-induced spin liquids with ⅑ magnetization have been predicted [
 1]. However\, the lack of ideal model materials and the difficulty of prec
 ise measurements under ultra-high magnetic fields of around 100 T have pr
 evented experimental verification of these rich theoretical predictions. W
 e succeeded in synthesizing a novel model quantum kagome antiferromagnet\,
  InCu₃(OH)₆Cl₃ (In-kapellasite). It crystallizes in the trigonal spa
 ce group P31m with lattice constants a=12.3235 Å and c=6.0347 Å and 
 a kapellasite-type kagome network [2]. Although the kagome network is sli
 ghtly distorted because Cu forms two different isosceles triangles\, there
  is a three-fold axis on the In site\, which marks a significant differenc
 e from other distorted kagome materials [2]. The antiferromagnetic Curie-
 Weiss temperature and effective magnetic moment of In-kapellasite are esti
 mated to be ΘW=–12.8 K and peff=2.05\, respectively. Short-range order
  occurs at 7 K where the magnetic susceptibility exhibits a slight upturn
  and the heat capacity shows a broad peak. Subsequently\, long-range magne
 tic order develops at 1.8 K\, evidenced by a sharp peak in the heat capac
 ity. In high-field magnetization measurements up to 50 T\, the full magne
 tization process to saturation was observed. Interestingly\, a ⅓-magneti
 zation plateau is observed at relatively low fields of ~7–14 T.</p> <p>
