The thermal expansion coefficient of Nd-Fe-B and Sm-Co permanent magnets in the region of the Curie point

The thermal expansion coefficient of Nd-Fe-B and Sm-Co permanent magnets in the region of the Curie point

A dilatometric study results on the linear thermal expansion coefficient (LTEC) of Nd-Fe-B and Sm-Co permanent magnets are presented. The experimental data in the temperature range 200–750 K and 293–1163 K, respectively, are obtained. The measurements were made with an error 3%. The character of the...
