Abstract
Increasing the remanence value of bulk permanent magnets is a critical issue to increase their maximum energy product ((BH)(max)) value. Currently, the enhancement of magnetic alignment is known to come close to the engineering limit. In this study, we investigated the effect of a magnetic layered structure on the remanence value using strontium ferrite and AlNiCo. Through the thickness control of AlNiCo layers, the magnetic properties of the layered composite magnets were evaluated. As a result, the remanence value increased from 4.13 kG to 4.32 kG and the maximum energy product value increased from 3.90 MGOe to 4.23 MGOe with the 5 wt% addition of AlNiCo.
