Abstract: We have studied the angular dependence of the irreversible magnetization of several YBa2Cu3O7 and 2H-NbSe2 single crystals with columnar defects tilted off the c axis. At high magnetic fields, the irreversible magnetization M-i(Theta) exhibits a well-known maximum when the applied field is parallel to the tracks. As the field is decreased below Hsimilar to0.02H(c2), the peak shifts away from the tracks' direction toward either the c axis or the ab planes. We demonstrate that this shift results from the misalignment between the external and internal field directions due to the competition between anisotropy and geometry effects.
