Ad Hoc Conference on FeNi₃
(MIT Digital Computer Laboratory, 1953-03-25)
The undersigned continued the discussion on FeNi₃ initiated by Dudley Buck at the seminar on magnetism, the meaning of order-disorder and entropy were examined. Hysteresis loops, saturation magnetization and Curie point ...

(MIT Digital Computer Laboratory, 1952-10-31)
On October 28, 1952, D. R. Brown, P. K. Baltzer and D. A. Buck of this laboratory visited the Bell Telephone Laboratories at Murray Hill, New Jersey, to discuss magnetic materials research with the following Bell men: R. ...
Magnetic-Core Memory Matrix Analysis (Effect Of Driver Impedance)
(MIT Digital Computer Laboratory, 1952-01-24)
The following analysis of a magnetic-core memory shows the extent to which the quiescent internal impedance of the row and column drivers affects the selection ratio.
The Ferroelectric Switch
(MIT Digital Computer Laboratory, 1952-04-16)
A multi-position ferroelectric switch is proposed which can accomplish many of the switching tasks in an information handling system; in particular, it can select among rods and columns of a ferroelectric memory. The logical ...

(MIT Department of Electrical Engineering, 2009-05-08)
Progress Report to the Department Committee on Graduate Study and Research on an Investigation of Ferroelectrics for Digital Information Storage
Group 63 Seminar on Magnetism, XLIV
(MIT Digital Computer Laboratory, 1953-03-26)
This memo is a summary of a Group 63 seminar on magnetism. Topics include the Hartree and Hartree-Fock methods of arriving at a self-consistent field determination.
West Coast Trip, July, 1953
(Lincoln Laboratory - Division 6, 1953-07-31)
A recent trip to the West Coast included visits to several laboratories engaged in the development of magnetic materials for digital-computer applications. Evaporated molybdenum Permalloy cores at NBS, Corona, have rectangular ...
Matrix Driving with Unidirectional Pulses
(MIT Digital Computer Laboratory, 1953-02-25)
Modification of the driving scheme during either the READ or the WRITE part of the READ-WRITE cycle would allow unidirectional current pulses in the rows and columns of a magnetic-matrix memory. This modification involves ...
Trip Report of Visit to Bell Telephone Laboratories, IBM, Glenco Naval Research Laboratory and Dr. C. F. Pulvari
(MIT Digital Computer Laboratory, 1952-07-17)
A trip was made at the conclusion of the thesis work on ferroelectrics for digital information storage and switching to compare progress and to exchange ideas with other researchers in this field. In addition, one visit ...
Binary Counting With Magnetic Cores
(MIT Digital Computer Laboratory, 1951-12-06)
Magnetic materials suitable for multi-dimensional memories have recently become candidates for circuit elements in other parts of a digital computer. Their possible uses in binary counters and as pulse-operated gates are ...
