The effect of the heavy-ion irradiation and the neutron irradiation on the magnetization behavior of RE123 (RE: Nd,Sm) single crystal was compared. The neutron irradiation introduces the spherical cascade defects, whereas the heavy-ion irradiation creates the columnar defects which penetrates throughout the sample. Both kinds of irradiation cause the enhancement of magnetic irreversibility, indicating that the introduced defects work efficiently as pinning centers.
