ジャーナル オープンアクセスLayers composed of Fe-Co-B layer and Ni-Fe (/Si) underlayer were prepared to increase the magnetic anisotropy field Hk for a greater signal to noise ratio (SNR). Fe-Co-B films with saturation magnetization Ms of 23 kG deposited on Ni-Fe seedlayer exhibited a low Hc of 0.6 Oe in the hard axis and a very high Hk of about 300 Oe. The magnitude of Hk depends on the condition of Ar gas pressure. The direction of depositing particles had an important role in the magnitude and direction of Hk. we proved that the mechanism to increase Hk : The magnetoelastic effect organized the difference of in-plane lattice spacing.抄録全体を表示PDF形式でダウンロード (171K) -

ジャーナル オープンアクセスThis paper presents a dynamic simulator for analyzing various behaviors of capacitance-drive-type linear electromagnetic solenoid (LES). The simulator enables short time analysis of dynamic response of LES compared with conventional simulation methods such as finite element method (FEM). To realize fast calculation of LES models, whole LES system including electromagnetic circuit, and mechanism are described and modeled by derivative equations. The short time analysis by the dynamic simulator allows LES designers to test various changes of parameters of a LES. In the individual sections, dynamic modeling of LES and the simulation algorithm using the mathematical models are described in detail. The simulator results are compared to the experimental results, and the validity of the simulator is verified.抄録全体を表示PDF形式でダウンロード (133K)
