Disturb properties of exchange-coupled composite plated wires

Disturb properties of four-layered films of Permalloy and Co-Ni alternately electroplated onto 0.1-mm diameter wires are reported. NDRO behaviors with various kinds of disturbs are shown. It is found that word disturbs intervening between digit disturbs are very influential. The mechanism in this case is different from that of wall creeping previously reported. Static changes of magnetization or hysteresis by intervening word pulses play an important role in the former case, although in the latter case dynamic changes of magnetization do. Some strange disturb behaviors are also found. These composite films have a wide operating region for NDRO.
