- Аннотация: We have measured the resistivity and Hall effect of R2Fe 17 (R=Y, Tb, and Gd) single crystals in the temperature T range 4<T<300 K and applied magnetic fields of up to 9 T. The anomalous Hall effect (AHE) is very anisotropic in these ferromagnets. The AHE resistivity, measured with an applied magnetic field H perpendicular to the c axis, is very large and varies quite linearly with the longitudinal resistivity ПЃ, but the AHE resistivity for H along the hard magnetization direction (Hc axis) is much smaller and increases as ПЃ2. We argue that the latter is of the intrinsic origin and is brought about by quasidegenerate Fe d levels near the Fermi level. В© 2011 American Physical Society.
