Abstract

The isotope ' Nd has been oriented by means of low-temperature nuclear orientation on the pseudobinary series Ce"Nd& "Ni for x =0. 0, 0.1, 0.25, 0.5, and 0.8. The results show that the compounds are magnetically ordered due to Nd-Nd interactions and no magnetic moment exists on cerium. The Kondo effect is present (for x@0)as revealed by measurements of electical resistivity and thermoelectric power.

Measurement of Seebeck effect (thermoelectric power) at high pressure up to 40 GPa

“…7a); this agrees with the other studies [61][62][63][64][65]. On the first pressurization cycle the pressure dependencies of the thermopower of CeNi samples (#1 and #2) exhibit distinct kinks near P$ 4-5 and $ 9-11 GPa (Fig.…”

“…CeNi is the simplest representative of the family of CeNi x (x¼1, 2, 2.33, 3, 3.5, 4, 5) heavy fermion alloys [52][53][54][55][56][57][58][59][60], and has the highest ambient thermoelectric power value among them, S $ +27 mV/K [61,62], $ + (21-27) mV/K [63], $ +28 mV/K (in Ce 0.8 Nd 0.2 Ni) [64], and only $ +15 mV/K in Ref. [65].…”
