摘要: Abstract Mechanically milled Pr4.25Tb1Fe71Co2.5Cr3B18 has been annealed to produce a material comprising (Pr,Tb)2(Fe,Co)14B hard phase intimately mixed with (Fe,Cr)2B and α-Fe soft phases. Susceptibility magnetic viscosity measurements have used characterise the reversal process in temperature range 20–300 K.
