| dc.description.abstractEn | The new high temperature form (HT) of the ternary germanide CeTiGe was prepared by annealing at 1373 K. The investigation of HT-CeTiGe by x-ray powder diffraction shows that the compound crystallizes in the tetragonal CeScSi type structure (space group <i>I</i>4/<i>mmm</i>; <i>a</i> = 414.95(2) and <i>c</i> = 1590.85(10) pm as unit cell parameters). Electrical resistivity, thermoelectric power, magnetization and specific heat measurements performed down to 2 K on HT-CeTiGe reveal a non-magnetic strongly correlated electron system; the specific heat divided by temperature attains a value of 0.635 J mol<sup> − 1</sup> K<sup> − 2</sup> at 2 K. The comparison of the physical properties of the two crystallographic modifications of CeTiGe suggests a decrease of the hybridization <i>J</i><sub>cf</sub> between 4f(Ce) and conduction electrons in the sequence LT-CeTiGe... | |
