“…The value of the free Tb ion is 9 B m . This value was close to the result of Hong et al [3] ( C T = 19 K and m (TbNi 4 B) = 6.3 B m /f.u.). In this paper we continue our investigations of the RNi 4 B compounds [2, 4 -8].…”

The electronic structure of the TbNi 4 B compound has been studied by the X-ray photoemission spectroscopy and ab-initio calculations. The experimental valence band spectrum as well as the calculated density of states exhibit the domination of the Ni(3d) states close to the Fermi level. The Tb(4f) peaks are well localized. The peaks' positions are in a good agreement with the binding energies of the metallic terbium and nickel. Our calculations show that the TbNi 4 B compound is ferromagnetically ordered. The contributions of Tb and B to the densities of states at the Fermi level are very small.

“…4b). Unfortunately, in the studies of magnetic properties [9] PrNi 4 B revealed the presence of an additional ferromagnetic phase of Pr 2 Ni 7 characterized by T C = 85 K. The problems with preparation of a single phase PrNi 4 B compound were also reported by other groups [20]. The electrical resistivity measurements confirm this observation because above 85 K a curvature is visible (Fig.…”

Electrical resistivity studies of RNi 4 B compounds (R = Y, Ce, Pr, Nd, Sm, Dy, Ho, Er) are presented. The ordering temperatures are well established in the case of the ferromagnetic compounds. YNi 4 B shows a presence of an impurity carbon-rich phase with a transition to the superconducting state at temperature of 12 K. This compound was treated as the isostructural non-magnetic reference compound for the RNi 4 B series. CeNi 4 B reveals a shallow Kondo-like minimum at low temperatures. Spin-disorder contributions are derived for the compounds and the resistivity in the ferromagnetic region is analysed including the influence of anisotropy effects. In the case of SmNi 4 B the effect of the crystal field was taken into consideration.

“…In contrast, when R is a heavy rare-earth element (J = L + S) the total rare-earth moment is coupled anti-parallel to the transition moment [1]. These materials are still attracting a great deal of interest due to the observation of a very large anisotropy in SmNi 4 B [2,3] and the discovery of a superconducting phase within the YNi 4 B alloy [4]. SmNi 4 B shows an exceptionally large and sharp cusplike ferromagnetic transition temperature, T C = 39 K and large coercive field (larger than 7 T) which is attributed to the effect of narrow domain walls [1] and the presence of a large magneto-crystalline anisotropy [3].…”

Physical properties of the Sm 1−x Tb x Ni 4 B (0 ≤ x ≤ 0.8) compounds have been investigated by means of the X-ray powder diffraction, AC-susceptibility and DCmagnetization techniques. All the compounds studied crystallize in CeCo 4 B-type structure with P6/mmm space group. The substitution of Tb for Sm leads to a decrease of the unitcell parameters a, c and the unit-cell volume V . The magnetic phase transition temperatures are found as 39, 30, 26, 22 and 15 K, for x = 0, 0.2, 0.4, 0.6 and 0.8, respectively. In addition, we have seen the second magnetic phase transition around 230 K, at the ac-susceptibility results. We have concluded that this behavior may arise from the Tb-Tb interaction in crystal structure.
