From: Unveiling the origin of the large coercivity in (Nd, Dy)-Fe-B sintered magnets
a Initial magnetization and demagnetization curves and b angular dependences of the coercivity of Dy-free and Dy-containing samples. For comparison, the angular dependences of the coercivity for the Kondorsky (1/cos(θ)) and Stoner–Wohlfarth models ((cos2/3(θ) + sin2/3(θ))–3/2) and the gray dotted line for Hc(θ)/Hc(0°) = 1 are also plotted in (b).
