Abstract

Experimental data on the use of rare earth metals in combination with cobalt as the basis of permanent magnets are presented. Data analysis and calculations of the functionality of such magnets show that such magnets will have noticeably higher stability and will demonstrate unusually small deviations of properties under temperature variations. The proposed magnets will significantly increase the signal-to-noise ratio when removing the signal from the electrodynamical devices.
