Abstract

Strips of cold-rolled gadolinium have been produced starting from an ingot of 99.9%-pure metal. The rolling has been carried out in a particularly severe regime, the thickness has been reduced 550 times. The rolled strips feature significantly (several times) diminished ΔTΔT and ΔSΔS effects, as well as a very large induced magnetic anisotropy, estimated to be between 10 and 15 MJ/m3.
