Physical properties of the RNi4Cu (R=rare earth) compounds

First principles study of electronic structure of CeNi4Cu

“…and q ¼ ÿ11.7 K [4]. The value of the effective moment is in good agreement with result obtained by Musil et al [10], where the paramagnetic behaviour of the compound has also revealed down to T ¼ 2 K. The effective moment obtained earlier by Pedziwiatr et al [11] for CeNi 4 Cu (m eff ¼ 0.13 m B ) is smaller than that in Refs.…”

“…It has been shown in Ref. [4], the resistivity behaviour of CeNi 4 Cu is typical of a Kondo impurity system.…”

“…The value of the effective moment is in good agreement with result obtained by Musil et al [10], where the paramagnetic behaviour of the compound has also revealed down to T ¼ 2 K. The effective moment obtained earlier by Pedziwiatr et al [11] for CeNi 4 Cu (m eff ¼ 0.13 m B ) is smaller than that in Refs. [4,10]. The above mentioned values of the effective magnetic moment are much lower in comparison with the free Ce 3þ ions value which is equal to 2.54 m B .…”

Neutron diffraction and X-ray photoemission studies of the RNi4Cu compounds (R = Ce, Pr, Nd)

“…We have intensively studied the RNi 4 M series (e.g. [2,3]). The RNi 4 Cu compounds differ from the remaining M substitutions by the reason of the Cu(3d) states being close both to the Fermi level (E F = 0) and the Ni(3d) (∼ −0.7 eV) states.…”

Magnetic properties of hexagonal RNi4Si (R=rare earth) compounds

“…Recently, we have intensively studied the RNi 4 Al and RNi 4 Cu compounds [1][2][3][4][5], where R denotes a rare earth. In our previous paper [6] we presented results of magnetic measurements for RNi 4 Si with R = Ce and Yb.…”
