Soft magnetic devices applied for low zero excursion (0.01°/h) four-mode ring laser gyro

Soft magnet devices have a wide variety of applications in aerospace, military, and industrial sectors. Generally, devices used in industrial applications are required to operate satisfactorily under ambient temperatures of +10 degrees C to +50 degrees C under normal pressure, whereas those used in aerospace and military applications will face a wider range of temperatures from -60 degrees C to +80 degrees C and generally high pressure. In most of the soft magnetic materials, the use of a temperature compensating and stress-sensitive alloy will introduce changes in their normal performance. Therefore, an attempt is made to devise a method that ensures inherent temperature compensation and stress proof. Recent work in characterizing the performance of multielement high-entropy magnetic nanocomposite systems will be described. Specifically, we have developed soft magnetic alloys that exhibit tolerance of high stress and large temperatures changing above current operating ranges for four-mode ring laser gyro (RLG) devices.
