Effects of Zr addition and magnetic field process on the superconducting property of HoBa 2Cu 3O 7-x films fabricated by a chemical vapor deposition technique in magnetic fields have been investigated. It is found that Zr additions lead to improvement of the critical current density J c in-field, while a further J c enhancement along the c-axis of the HoBa 2Cu 3O 7-x films is obtained in magnetic field processed samples. The nano-particles and nano-rods induced by the Zr addition are thought to account for the in-field J c improvement. In addition, it seems that there are more columnar defects in the samples deposited under magnetic field than the normal samples, which in turn enhance the pinning ability along the c-axis.
