In many permanent magnet applications, there are regions in the magnet volume where the magnetic field acts at large angles to the direction of magnetization. The hysteresis curves, however, are determined almost exclusively with the magnetic fields

Segmenting rare earth permanent magnets into thin slices is an effective means for avoiding eddy current losses in oscillating magnetic fields. However, the large surface areas created by segmentation can give rise to severe hysteresis losses. The su

This paper reports the room temperature hydrogen decrepitation (HD) of fully dense, 2/17-type sintered magnets based on the composition, Sm(Co 0.69 Fe 0.21 Cu 0.068 Zr 0.019 ) 7.49 . These magnets absorb significant amounts of hydrogen over an extend

The stability of the magnetic properties of Sm/sub 2/Co/sub 17/-type magnets at high operating temperatures was investigated by magnetic measurements at room temperature (RT) and high temperatures (HTs). The coercivity at RT is changed by the HT meas

The influence of the chemical composition on the microstructure of high-temperature Sm(Co,Fe,Cu,Zr)z magnets is examined in this study. A completely developed cellular preciptation structure is the key factor for a high coercivity. Changing the chemi

The dependence of the coercivity on the maximum applied field is found to be mainly dominated by the distribution of the critical fields originating from the grain misalignment. For aligned magnets the coercivity reaches its saturated value at a magn
