Materials Research for Advanced Inertial Instrumentation. Task 3. Rare Earth Magnetic Material Technology as Related to Gyro Torquers and Motors.

Abstract

For inertial applications, high-energy-product SmCo5 magnets are required which possess very low flux decay rate, near zero temperature coefficient of magnetization, and thermal expansion coefficient similar to that of beryllium. Concentrated effort has been directed towards achieving and understanding the underlying mechanism of high flux stability. In the ensuing period, efforts will be directed towards temperature compensation and tailoring of thermal expansion along with further studies on stability. (Author)
