“…4, the low temperature detail of the heat capacity measurement on GdNi 5 under different applied magnetic fields is presented. We observe an anomaly at T C = 31 K, which is the trademark of transition into the magnetically ordered state, in agreement with previous data [2,[5][6][7]. One can see that the applied magnetic field is depressing the intensity of the peak without changing its position.…”

“…3, the magnetization as a function of the applied magnetic field at 2 K is presented for all compounds to see the Ce influence. The saturated magnetization for GdNi 5 is in agreement with previous data [6,7]. The values of M SAT are decreasing with increase of x, reaching 1.33 µ B /f.u.…”

“…The measured magnetic properties of GdNi 5 are again in a very good agreement with previous data in literature [2,[5][6][7]. At a small applied magnetic field, B = 0.01 T, a maximum with a small hysteresis is present at T C = 31 K. An applied magnetic field of 1 T smears out the maximum and produces an inflexion point at the same transition temperature.…”

“…Determined lattice parameters are summarized in Table I. Data for GdNi 5 are in an agreement with previous data [2,[5][6][7]. We observed only a small decrease of a and a small increase of c with increase of Ce content.…”

“…However, CeNi 5 is a Stoner enhanced paramagnet characterized by the influence of spin fluctuations (SF) on its properties [3], where SF originate from the Ni atoms [4]. On the other hand, GdNi 5 is known as a ferromagnetic compound with T C = 31.8 K [5][6][7], where one can expect a doublet CEF ground state. Therefore, Gd 1−x Ce x Ni 5 is an interesting intermetallic system, where it is possible to study the competition of SF interactions and CEF effects.…”

We have prepared a new system of Gd1−xCexNi5 polycrystalline samples with concentrations x = 0, 0.2, 0.5, and 0.8 in order to study the influence of different rare-earths substitutions on the ground state connected with spin fluctuations. GdNi5 is a ferromagnetic compound with TC = 31.8 K and CeNi5 is a well-known spin fluctuation compound without magnetic ordering down to the lowest temperatures. X-ray diffraction study confirms the hexagonal crystal structure and the single phase samples. Magnetic properties (M (T ), M (B)) show that an increasing content of Ce depresses the transition temperature, TC, down to 4.9 K for x = 0.8. The heat capacity measurements confirmed these results.

The effect of Cu-doping on the electronic structure and optical properties of intermetallic compounds (Ho,Er)Ni 5Àx Cu x (x ¼ 0, 1, 2) has been studied. Band structure and interband optical conductivity were investigated theoretically using the LSDA þ U method supplementing local spin density approximation with a correction for strong electron interaction on the 4f shell of rare earth element. Optical properties were studied by the ellipsometry method in the spectral range 0.22-15 mm. It was found that substitution of Cu for Ni atoms in these alloys leads to significant changes in the frequency dependence of the optical conductivity. Both the theoretical calculations and spectroscopic experiments revealed the appearance of a new absorption maximum near 4.5 eV formed by Cu 3d ! Ni 3d interband transitions.
