“…Of special interest are the properties of TE in applied magnetic field. For example, some superconductors like Ba 1−x K x BiO 3 , BaP b x Bi 1−x O 3 and La 2−x Sr x CuO 4 were found [10] to exhibit anomalous temperature behavior of both magnetostriction and TE which were attributed to the field-induced suppression of the superstructural ordering in the oxygen sublattices of these systems.…”

“…T c2 = 10 K, obtained from various experiments on heat capacity, thermal expansion, and thermal conductivity [27] in MgB 2 , which yields e 2 =c 1 c 2 ¼ ð3=8ÞT 2 c . Note that, based on the experimental results it has been argued in the extensive review by Buzea and Yamashita [28] that T c1 /T c2 ' 2.…”

“…There has been an intensive study of almost all the types of physical properties of the MgB 2 superconductor in both the super conducting and normal states, and thus sufficient progress has been made to understand the behavior of this compound [5]. In particular, the thermal conductivity has been investigated by a large number of workers [6][7][8][9][10][11][12][13][14][15][16] by considering various forms of the MgB 2 system, like different defect levels, different types of doping, and single or polycrystalline samples. The studies of the thermal conductivity (κ) of MgB 2 made by Sologubenko et al [9,13], Wu et al [15] and Anshukeva et al [16] is limited to low temperatures (T ≤ 100K) only and in these studies κ increases with temperature T within the considered temperature range.…”

Other authors [6-8, 10-12, 14] have studied the thermal conductivity up to much higher temperature range (T ≤ 250K [7], T ≤ 275K [10,11], T ≤ 300K [6,8,12,14]).…”
