摘要:
Disclosed is the addition of at least two elements of Nb, V, Ta and Zr to the ternary alloy of R (rare earth)-Co-Cu for permanent magnet materials, to thereby provide the permanent magnets with increased coercive force, residual magnetization and energy product. The additional elements enable employment of such Cu and Fe contents of the alloy as less than 10% and more than 6%, respectively. These percentages were avoided in the prior art to prevent the reduction of Br and Hc, respectively.

摘要:
The present invention relates to a saturable core which consists of a coiled thin strip of an amorphous magnetic alloy. The present invention provides a saturable core having a high .DELTA.Bs, a low power loss, a good saturation property, and low secular changes of the magnetic properties, due to determining the coiling direction of the saturable core so that it is the same as that of a coil heat treated.
