New Metallic Cores from Magnetic Metals, 1953 January 2
MIT DIC 6889. Project Whirlwind Engineering Note E-518. A preliminary test on 12, 1/4-mil molybdenum permalloy cores from Magnetic Metals indicates that signal ratios are unsatisfactory for memory application. Disturbed-one-to-disturbed-tero ratio is about 35; disturbed-one-to-delta-one* ratio is about 50; and disturbed-one-to-delta-two* ratio is about 250. A slight disturb sensitivity was observed at moderate currents for most cores tested. Improved uniformity, however, is indicated.

The Incorporation of a Magnetic Matrix Switch into a Multiplanar Coincident-Current Magnetic Memory, 1953 November 12
Project Whirlwind Memo M-2514. Master's Thesis Research Proposal on the Incorporation of a Magnetic Matrix Switch into a Multiplanar Coincident-Current Magnetic Memory. The purpose of this thesis is to investigate the problem of driving a large (64 x 64 x 32 digit) coincident-current magnetic-core memory using magnetic switch cores.
