“…However, this problem is not so simple, becaUSj~ the single crystalline ~dos)Fes phase, if it exists, probably has an easy-plane anisotropy. Tb z Fen has reported as an easy-plane ferrimagne~t [8], which has very similar structure with TbFes or (TbosG<Ios)Fes and should have the similar property _ Therefore, there is quite an inconsistency between our results and the single crystalline property. As a measure to explain it, we examined the electronic property of these films.…”

-Microstructure and the electronic property of amorphous (Tbo.sGdo.5)X Fe1oo-x (X = 10-30) films with a giant perpendicular magnetic anisotropy (GPMA, the uniaxial anisotropy constant Ku =-10 7 erg/emS) have been studied in detail. As a result it is found that these films consist of large "crystals" of which the local atomic arrangement is similar to GdFe5 (CaCu;;-type, hexagonal) and their c-axes orient in the normal direction to the film plane. Therefore, the GPMA is considered to be generated from the" crystalline" phase. Considering the large electrical resistivity of these films, perpendicular anisotropy is probably induc(~d by the random pair formation of neighboring rare earth (RE=Tb,Od) atoms in the <001> direction of the REFe5 structure.

“…A first-order magnetization process is observed at a magnetic field of about 2.5 T applied along the sixfold axis in Tb 2 Fe 17 . 18 The critical field for this transition is nearly independent of temperature up to ≈250 K even though the anisotropy constants vary with temperature, as expected from existing models. 19 In this paper we report results of the Hall effect, resistivity, and magnetization measurements in R 2 Fe 17 (R = Y, Tb, and Gd) single crystals for wide temperature and applied magnetic field ranges and for various magnetic field orientations with respect to the easy-magnetization axis.…”

We have measured the resistivity and Hall effect of R 2 Fe 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 ρ, but the AHE resistivity for H along the hard magnetization direction (H c axis) is much smaller and increases as ρ 2 . We argue that the latter is of the intrinsic origin and is brought about by quasidegenerate Fe d levels near the Fermi level.

“…The Tb sublattice couples antiferromagnetically to the Fe sublattice in the Tb 2 Fe 17 alloy. A first-order magnetization process (FOMP) is observed at a magnetic field of about 2.5 T applied along the sixfold axis in this compound [5]. The FOMP does not affect the mutual orientation of the sublattices only their relative orientation to the crystallographic axes.…”

We have performed measurements of the Hall effect, electrical resistivity, and magnetization on Tb2Fe17 single crystals in the 5 to 300 K temperature range, and in magnetic fields of up to 5 T. We find that the anomalous Hall effect of this ferromagnet depends strongly on the magnetization direction relative to the crystal axes. The AHE resistivity, measured with an applied magnetic field H perpendicular to the c-axis, is very large and varies linearly with the longitudinal resistivity ρ, whereas the AHE resistivity for H along the hard magnetization direction is much smaller and increases as ρ 2. For the latter configuration, the electrical resistivity shows a sharp decrease at a field-induced first-order magnetization process (FOMP) which is observed in H ∼ 2.7 T up to a temperature of 250 K.
