Klein and E. Kneller Max-Planck-Institut für Metallforschung, Stuttgart, Germany Received 18 October 1965 The magnetocrystalline anisotropy constant K1 of iron was determined from static torque measurements on a {001} single-crystal disk at fields between 3000 and 18 000 Oe, and at temperatures between 77 and 900°K. It was found that (i) ( [partial] K1 / [partial] T) / K1~=10( [partial] M / [partial] T) / M above 300°K, in agreement with Zener; (ii) ( [partial] K1 / [partial] H) / K1~=22( [partial] M / [partial] H) / M below 600°K, and at H~=10 KOe; and (iii) ( [partial] K1 / [partial] H) / ( [partial] K1 / [partial] T)~=-1.25 x 10-3°K/Oe over the whole temperature range of this investigation. ©1966 The American Physical Society URL: http://link.aps.org/abstract/PR/v144/p372 DOI: 10.1103/PhysRev.144.372 ------------------------------------------------------------------------ View Page Images or PDF (522 kB) [ Previous article | Next article | Issue 2 contents ] ------------------------------------------------------------------------ References (Reference links marked with dot may require a separate subscription.) 1.
