Annotation	The addition of long-term Zr₂O₃-ball milled Gd₂BaCuO₅ particles to a standard (Nd,Eu,Gd)Ba₂Cu₃O_y superconductor led to a spontaneous formation of extremly small (20-50nm) Zr-rich (Nd,Eu,Gd)-Ba-Cu-O particles during the melt-hrowth process. This new pinning medium , approaching the interesting physical limit of point-like pins pins,resulted in magnetic levitation with liquid oxygen as a coolant.
