Nature of magnetic order in YbInNi4
  We have measured field and temperature dependent magnetization of YbInNi4 to elucidate the nature of the magnetic transition at 3 K. For small fields we find magnetic order as previously reported. In contrast to former reports, however, our high resolution magnetization measurements down to 500 mK indicate dominating antiferromagnetic exchange interactions. We discuss the presence of geometrical frustration.
