Hard magnetic and broadband microwave absorption characteristics of heat-treated PrDFeB(x = 0, 1, 2, and 3) alloys.

In this study, fabrication of PrDyFeB (at.%) alloys with x = 0, 1, 2, and 3 compositions was performed with a mini vacuum arc melting furnace. The alloys were successively annealed in an inert atmosphere for microstructure homogenization.
