(Y, Gd)Ba 2 Cu 3 O y and (Y, Eu, Gd)Ba 2 Cu 3 O y films with and without Zr addition are prepared. The effect of Zr addition on critical current density J c is different for the two series. Compared to (Y, Gd)Ba 2 Cu 3 O y films without Zr addition, J c ( B ) is clearly enhanced by adding Zr, especially in high field. But for (Y, Eu, Gd)Ba 2 Cu 3 O y films, the addition of Zr is disadvantageous to J c . Analysis indicates that the flux pinning mechanism is altered for (Y, Eu, Gd)Ba 2 Cu 3 O y films, whereas it remains the same for (Y, Gd)Ba 2 Cu 3 O y films after adding Zr.
