Hysteresis behavior and microstructure of exchange coupled R/sub 2/Fe/sub 14/B/sub 1///spl alpha/-Fe magnets

The hysteresis behavior of nanocomposite R/sub 2/Fe/sub 14/B//spl alpha/-Fe magnets with R=Nd and Pr was investigated at low temperatures. The room temperature coercivity depends on annealing with a peak value at 700/spl deg/C. The low coercivity of samples annealed at temperatures below the optimum...
