Effect of Uniaxial Compression on Exchange Interaction in SmCo and NdFeB Permanent Magnets
Main Article Content
Abstract
The dependence of the magnetization of a SmCo magnet on the uniaxial pressure up to 6.2 MPa was measured at T = 300 and 77 K. A diminishing of the magnetization was observed. The results obtained for the SmCo and NdFeB permanent magnets qualitatively correspond to the slope of the Berthe–Slater curve.
