Notes:
The magnetic anisotropy of permeability and high-field susceptibility in Ni3Fe single crystals due to dislocations and antiphase boundary (APB) was theoretically calculated and measured by a vibrating sample magnetometer to determine the cyclic hardening and deformation substructure during cyclic deformation. Two types of anisotropy in magnetic properties were observed due to the atomic rearrangement near APB and the internal stress field around dislocations. In an early stage of fatigue where strong cyclic hardening occurred, the magnetic anisotropy was mainly due to the APB, while in a further stage of fatigue where cyclic softening occurred, the anisotropy was caused by dislocations. The cyclic softening was induced by the disordering in the localized region of coarse slip bands. © 2000 American Institute of Physics.
