AIP Conference Proceedings, 1973
The authors have measured the magnetization of a polycrystal of an iron‐like material in weak fields. They show that the Rayleigh coefficients a and b depend on the type of demagnetization used, and they give the angular dependence and field behaviour of a and b.

A demagnetization circuit for Forward converters
2009 6th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology, 2009This paper presents a demagnetization circuit able to operate the forward converter with an higher efficiency and with a wider input range. In particular, by the means of few added components, the magnetizing energy and the leakage one are continuously recovered, and the transformer reset and the primary mosfet OFF voltage clamp to the input, both ...

Demagnetization of magnetically shielded rooms
Review of Scientific Instruments, 2007Magnetically shielded rooms for specific high resolution physiological measurements exploiting the magnetic field, e.g., of the brain (dc-magnetoencephalograpy), low-field NMR, or magnetic marker monitoring, need to be reproducibly demagnetized to achieve reliable measurement conditions.

The Bayreuth nuclear demagnetization refrigerator
Journal of Low Temperature Physics, 1987In this letter we report on the construction and operation of the new nuclear refrigerator at the University of Bayreuth. It contains two Cu stages of 103.5 moles in 8 Tesla and 2 moles in 9 Tesla, respectively. After demagnetization the first stage has cooled a Pt-NMR thermometer in the field free experimental region to 15 µK.

2024 Collaborative Network for Engineering & Computing Diversity (CoNECD) Proceedings
The lack of diversity in engineering programs has been a persistent problem in the US. One of the largest disparities in engineering enrollment is with Black students. It is crucial to address the unique challenges that Black students face in gaining admission to engineering programs. Despite the resources and effort committed to addressing this issue,

Experiments on adiabatic demagnetization
Physica, 1940Abstract It is found that the temperatures calculated from the magnetic susceptibilities of three different paramagnetic salts are in agreement with the temperature scale of Bleaney and Simon. The Stark splitting of KCr(SO4)2.12H2O. derived from the demagnetization experiments is = 0.263 degrees, that of Cr(NO3)3. H2O δ = 0.283.

An Improved Operating Room Demagnetizer
Archives of Ophthalmology, 1977An operating room demagnetizer that utilized a pulsed, smoothly decaying oscillating magnetic field is described. The instrument can demagnetize a number of surgical instruments at one time and can provide instantaneous and complete demagnetization.

Stress demagnetization in videotapes
IEEE Transactions on Magnetics, 1982Experience with helical-scan videotape recorders has shown that the mechanical forces involved in handling the tape are sometimes sufficient to cause significant reductions in signal level due to stress demagnetization. A tape-loop recorder was used in an investigation of stress demagnetization in videotapes.
