LONG-TERM MAGNETIC STABILITY OF Sm-Co MAGNET FOR THE ACCELRATOR APPLICATIONS

Abstract

A comparison of measurements of the topology of the magnetic field of a permanent magnet made using the rare earth alloy Sm2Co17, carried out at an interval of 5 years, was made. The data obtained in 2023 indicate that the metrological characteristics of the magnet remained within the limits that were determined in the studies conducted in 2018.
