Effect of stress induced anisotropy on SAL-biased MR head performance
The effect of magnetostriction (MS) on the device characteristics of soft-adjacent-layer (SAL) biased magnetoresistive (MR) head was investigated. As MS changes from -7/spl times/10/sup -7/ to 1.77/spl times/10/sup -6/, the magnetic track width increases from 1.26 to 1.83 /spl mu/m. Asymmetry of bias point, output sensitivity, and output amplitude are also affected by the stress induced anisotropy. The variation of magnetostriction (/spl Delta//spl lambda/=2/spl times/10/sup -6/) induces the change in bias field by 60 Oe associated with the estimated stress of +800 MPa on the MR stripe.
Sub-milli-Torr magnetron sputter deposition of magnetic thin films
In this paper, we evaluate the single films stress of various component layers in spin-valve or magnetic tunnel junction multilayers and the magnetic thickness loss due to interlayer atomic mixing in the magnetic thin films deposited by sub-milli-Torr magnetron sputtering with that from ion beam sputtering.
Nonprofit Communication and Fundraising in China: Exploring the Theory of Situational Support in an International Context
Using a survey of 586 college students from Beijing, China, this study tested the theory of situational support by exploring Chinese students’ motivations to participate in nonprofit fundraising events. This study also compared theory variables between Chinese and U.S. college students by looking at similar data from a survey previously conducted with 514 U.S. students. There were differences between the two groups regarding constraint recognition, subjective norms, attitudes toward fundraising, and other variables, perhaps because of Confucianism, collectivism, and other differences between China and the United States. The findings generate a range of theoretical and practical implications including how nonprofit practitioners in China might develop better communication and messaging strategies to segment publics, motivate potential donors, and advance future fundraising efforts.
