Influence of demagnetization in remanence curves of magnetic thin films
Remanent magnetization curves of perpendicular magnetic thin films are simulated and measured. The simulations are used to investigate the theoretical influence of the strong demagnetizing field present in these films. Conclusions are drawn from this on how remanence curves should be measured and how they should be corrected for the demagnetizing influence. The experimental part consists of measurements on Fe‐Alumite, Co‐Pt–based multilayers, and Co‐Cr. In addition the latter material is also artificially patterned into microstrips in order to investigate the influence of demagnetization on remanence curves experimentally.
Magnetic interactions in CoCr thin films
Both the isothermal remanent magnetization and the dc demagnetization remanence were measured on thin films of CoCr with a perpendicular anisotropy energy suitable for perpendicular recording media. The measurements were made with two applied magnetic field geometries, parallel and perpendicular to the film plane. Plots of the dc demagnetization remanence versus the isothermal remanent magnetization were used to determine the presence of interactions for both applied magnetic field geometries. As expected, the perpendicular magnetization process is dominated by the demagnetization field. When the data are corrected for the demagnetization field, a residual negative interaction is found from the perpendicular data. This negative interaction was also observed in the parallel applied field geometry plots, where the demagnetization factor is negligible. The success of the analysis, using a mean‐field approximation to model the interactions, which in this case is the demagnetization field, suggests a general t...
Mentally disordered offenders and the law: Research update on the insanity defense, 2004-2019.
The insanity defense is among the most controversial legal constructs that has attracted the attention of scholars, practitioners and policy makers. Here, we conducted a systematic review of the literature spanning 2004 to 2019 that produced 58 studies of insanity defense research. Findings are organized according to: (1) assessments and assessment-related issues, (2) juror decision-making in defense trials, (3) characteristics of insanity acquittees, (4) release recommendations for insanity acquittees, (5) revocation of conditional release status of insanity acquittees, and (6) additional areas of insanity defense research. Implications of the research for the insanity defense and cognate legal issues are proffered.
