Abstract
The effect additives of TbAl3 hydride have on the magnetic properties and structure of sintered permanent magnets based on Pr–Fe–Co–Cu–B alloy with increased temperature stability is studied. Such magnetic properties as Br = 1.07 T, ВНmax = 216 kJ m−3, jHc = 2000 kA m−1, Hk = 1680 kA m−1, Hk/jHc = 0.84, and α = −0.030% °С−1 (in the temperature range of 20–100°C) are achieved.
