Effects of charged particles and neutrons on magnetic materials

A STATE-OF-THE-ART review through 1959 on effects of nuclear radiation upon magnetic materials was published by Gordon¹ in 1960. This paper supplements that review by summarizing the significant data since obtained at the Naval Ordnance Laboratory and elsewhere on reactor and charged-particle irradiation effects on both soft magnetic materials and permanent magnets. New results obtained by the authors on recovering magnetic properties of proton irradiated iron and 5–79 Mo-Permalloy also are presented.
