A single crystal CeNi 4.2 Mn 0.8 was grown by the Czochralski method from a levitating melt. The structural, magnetic, electrical transport and electronic structure properties were examined. X-ray diffraction confirms the hexagonal structure. The f occupancy n f and the coupling ∆ between the f level and the conduction states are derived to be about 0.95 and 100 meV, respectively. The X-ray photoemission spectroscopy shows that Ce ions in CeNi 4.2 Mn 0.8 are in the intermediate valance state. The temperature dependence of resistivity exhibits the metallic character of this compound and reveals a small inflection at 136 K.

“…The CeNi 4 X compounds are of special interest due to the nearly filled Ni (3d) band implying a negligible contribution of Ni atoms to the resultant magnetic moment [1][2][3]. In the temperature dependence of electrical resistivity we have observed a shallow minimum for CeNi 4 X below 20 K. It has been ascribed to a Kondo-like behavior.…”

“…We have previously studied the CeNi 4 X (X = Al, Ga, Si) [1][2][3], and CeCu 4 Al [4] compounds crystallizing in the hexagonal CaCu 5 -type structure, space group P 6/mmm. The CeNi 4 X compounds are of special interest due to the nearly filled Ni (3d) band implying a negligible contribution of Ni atoms to the resultant magnetic moment [1][2][3].…”

Heat Capacity of Heavy Fermion Compound CeCu₄Ga in High Magnetic Fields

The heat capacity in the applied magnetic field up to 9 T, susceptibility and magnetization of polycrystalline CeCu4Ga are presented. Magnetic ordering was not observed down to 2 K. For temperature T < 200 K a Curie-Weiss behavior is observable giving an effective magnetic moment µ eff = 2.53 µB/f.u. The experimental value of µ eff is close to the calculated one for a free Ce 3+ ion (µ eff = 2.54 µB/f.u.), thus indicating the presence of well localized magnetic moments carried by the stable Ce 3+ ions. At low temperatures the electronic heat capacity coefficient value depends strongly on the temperature range used for the extrapolation and applied magnetic field. We observe a typical heavy fermion behavior with γ value of about 380 mJ mol −1 K −2 obtained from extrapolation to T = 0 K of the temperature range above 7 K. However, extrapolation of the lowest temperatures range yields the γ value of 3.3 J mol

We report on the transitions between the ferromagnetic order, spin-glass behavior, heavy fermion and uctuating valence state in a series of isostructural compounds CeT4M (T = Ni, Cu; M = Al, Ga, Mn). The dilution of Ce or the T and M elements allowed us to follow the physical properties evolution employing the measurements of the heat capacity, dc magnetic susceptibility, frequency dependent ac magnetic susceptibility, magnetization relaxation, inelastic neutron scattering and also the X-ray photoemission spectroscopy. It is shown that the Mn rich compounds lean towards the spin glass behavior. For the compounds governed by the close to localization Ce 4f states the eect of the crystal electric eld has been studied. It has been shown that the spin glass-like behavior can signicantly inuence the physics of the CeT4M compounds.
