Efficient magnetic microactuator with an enclosed magnetic core

Journal of Micro/Nanolithography, MEMS, and MOEMS, 2002
An efficient spiral-type magnetic microactuator design, composed of an enclosed core and a magnetic plate, is presented to produce a high magnetic flux density, a large force, and a large displacement. The design allows a large variation in area of the Permalloy plate and then the area of the poles can optimally enlarge with the fixed area of the ...

Vortex Core-Driven Magnetization Dynamics

Science, 2004
Time-resolved x-ray imaging shows that the magnetization dynamics of a micron-sized pattern containing a ferromagnetic vortex is determined by its handedness, or chirality. The out-of-plane magnetization in the nanometer-scale vortex core induces a three-dimensional handedness in the planar magnetic structure, leading to a precessional motion of the ...

A new nondestructive read for magnetic cores

Proceedings of the March 1-3, 1955, western joint computer conference on - AFIPS '55 (Western), 1955
A simple but effective method has been developed for reading information from ferrite storage cores without destroying the information. A single ferrite core containing a small radial hole is used per stored bit. A wire is threaded through the hole and a current pulse is passed down the wire to interrogate the core.

A medium-speed magnetic core memory

Papers presented at the February 26-28, 1957, western joint computer conference: Techniques for reliability on - IRE-AIEE-ACM '57 (Western), 1957
The steady evolution of the state of the art in coincident current magnetic core memories leads constantly in the direction of an all-transistor system of appreciable proportions. Several organizations have been at work in this field, but the system herein described is the first of its type.

A Transistor-Driven Magnetic-Core Memory

IEEE Transactions on Electronic Computers, 1957
A transistor-driven magnetic-core memory which has a capacity of 1024 18-bit words has been built and is being studied. Both the read and write operations employ the coincident-current technique. The memory-drive currents are developed by transistors and the desired memory location is selected by magnetic-core selection switches.
