The Nd2CuO4-type Ca-doped rare-earth cuprates R t.s3Cao.~TCUO4 (R = Gd, Dy or Tm) have been synthesized under high pressure. Only that with the small ion Tm 3+ and thus the short Cu-O bonds ( 1.916 A) was superconducting (at about 30 K). This was considered to be the first example of p-type supercon
