Abstract: Flux jumps behavior in textured (Nd0.33Eu0.33Gd0.33)Ba2Cu3O7-δ (with high content of Gd-21 1 phase) have been studied. With the magnetic field parallel to the c axis, partial flux jumps have been obser ved in the temperature range 2—3K, and there were no jumps found above 5K. When ab plane is parallel to the field direction, no flux jumps have been observ ed in the whole temperature range (from 2K to Tc). The anisotropi c flux instability may be due to the anisotropic pinning force and geometrical demagnet ization factor. As the temperature increases,the number of flux jumps is decreas ed, and the third quadrant of M(H) curve is the most flux instability quadra nt. Finally we have studied the magnetic field sweep rate dependence of flux jum p, and discussed the influence of flux creep on flux jump.
