    Concentration of a magnetic field has been achieved using a Gd-Ba-Cu-O (GdBCO) magnetic lens. A conduction-cooled compact high-field superconducting magnet with a GdBCO magnetic lens was developed. The magnet possessed a 10-mm room-temperature bore and consisted of two Nb-Ti solenoid coils and a GdBCO magnetic lens, which was installed at the center of the Nb-Ti coils in order to concentrate the background field generated by the Nb-Ti coils. The Nb-Ti coils and the GdBCO magnetic lens were cooled using a two-stage pulse-tube cryocooler. A concentrated magnetic field of 10.3 T was obtained at a background field of 5.6 T provided by the Nb-Ti coils. No degradation was found in the magnet during repeat excitation. The large field gradient generated by the GdBCO magnetic lens is expected to be used for the levitation of diamagnetic materials.
