Thermal properties ofLu5Ir4Si10

Effect of Ba substitution on structural, electrical and thermal properties of La0.65Ca0.35−Ba MnO3 (0 ⩽x⩽ 0.25) manganites

“…Specific heat measurements were performed in temperature range 70-350 K using a high resolution ac calorimeter. The details of the thermal measurements techniques have been described elsewhere [28]. The parameters pertaining to the refinement are summarized in Table 1.…”

Substitutional effect on the transport properties of MnSi

“…Seebeck coefficient measurement was performed in a closed cycle refrigerator by a heat pulse technique. The details of the measurement techniques can be found elsewhere [4].…”

Hall coefficient studies in R5Ir4Si10 (R=Dy–Lu) near the charge–density–wave transitions

“…Note that their thermoelectric powers (S) remain positive at these temperatures [7]. On the other hand, the Hall coefficient for Lu is positive at all temperatures while its S changes sign from positive to negative at T CDW ¼ 80 K [4]. The difference in the sign of dominant carriers at low temperatures as obtained from the Hall coefficient and thermoelectric power data suggests that the R 5 Ir 4 Si 10 compounds are nearly compensated metals.…”

“…The phase transitions found in R 5 T 4 Si 10 system show very unusual physical properties compared to conventional CDW materials. For examples, the observed spike-shaped anomaly in C p in Lu 5 Ir 4 Si 10 exhibits the sharpest cusp with DT CDW =T CDW B1% (T CDW B80 K) among any reported CDW systems [3,4]. Besides, a clear thermal hysteresis (DT CDW B5 K) in Lu 5 Rh 4 Si 10 was observed near its CDW transition at T CDW B147 K [5,6].…”
