Group 63 Seminar on Magnetism, XLI
(MIT Digital Computer Laboratory, 1953-03-24)
This memo is a summary of a Group 63 seminar on magnetism. Topics include a study of the magnetization of alloys using the Heitler-London model, parallel spins, anti-parallel spins, nickel-manganese system, cobalt-iron and ...
Nucleation of Domains of Reverse Magnetization and Switching Characteristics of Magnetic Materials
(MIT Digital Computer Laboratory, 1953-03-09)
The critical requirements for a ferromagnetic memory core are reviewed. Domains of reverse magnetization must form and grow within a core if its induction is to be reversed. The nature of the nucleation centers for these ...
