本文研究了一类纳米晶合金HITPERM（Fe，Co）-M-B-Cu（M=Zr，Hf，Nb，etc.）被发现在本体中表现出优异的软磁性能，被用作垂直薄膜介质的软磁底层。Ti中间层用于促进（00 μ 2）织构并使磁性层（CoCrPt）与软磁底层交换解耦。将样品在室温和高温（约250 °C）下沉积。X射线衍射和透射电子显微镜结构的研究结果，沿着与磁性能。
In this work, a class of nanocrystalline alloys, HITPERM (Fe, Co)–M–B–Cu (M=Zr, Hf, Nb, and etc.) found to exhibit excellent soft–magnetic properties in bulk were used as soft–magnetic underlayers for perpendicular thin film media. A Ti intermediate layer was used to promote a (00⋅2) texture and exchange de-couple the magnetic layer (CoCrPt) from the soft-magnetic underlayer. Specimens were deposited at both room and elevated temperature (∼ 250 °C). The results of x-ray diffraction and transmission electron microscope structural studies, along with magnetic properties are presented.
