抄録

The induced uniaxial ferromagnetic anisotropy energy, E , as a function of the crystal orientation has been measured, using a torque magnetometer, with magnetically annealed (1\={1}0)-disc single crystals of 12 and 20%Ni-Co alloys. It has been found that, Eu may be well expressed by the formula<BR>(This article is not displayable. Please see full text pdf.) <BR>where K is a positive constant, k a numerical factor, and αi’s and βi’s (i=1, 2, 3) are the direction cosines of magnetization vectors during the torque measurement and during magnetic annealing, respectively, and that the factor k is 2∼3, being smaller than 4 as expected from the directional order theory for face-centered cubic lattice.
