摘要：
The dipole-dipole contribution to the anisotropy constant K1 in ellipsoidal single crystals of Y2Co17 and Gd2Co17 is calculated. The results are expressed in terms of closed formulae in which demagnetization factors occur explicitly. The formulae are used to show that the relatively large difference of K1 experimentally found in the two materials can largely be ascribed to the additional dipole-dipole interactions present in Gd2Co17.
