Abstract:
A possible mechanism in the anomalous Hall coefficient in mixed state of high-T c superconductors was presented in this paper. The Hall voltage due to flux creep is the origin of the observed Hall anomaly. The calculated Hall coefficient exhibits a sign change as well as a re-entry behavior, which agree with experiments, qualitatively.

Abstract:
We study the anomalous Hall effect in paramagnetic two-dimensional electron gas (2DEG) with both linear and cubic Dresselhaus spin–orbit coupling by means of Berry connection and Berry curvature. The effect of tuning the Fermi level and of tuning the cubic coupling coefficient on the anomalous Hall conductivity have been investigated semiclassically. Our results show that a sign reversal in the anomalous Hall conductivity may appear if the cubic Dresselhaus coefficient is very large and the Fermi surface is high enough, so the cubic Dresselhaus spin–orbit coupling term cannot be neglected in this case.

Abstract:
The Kondo effect is a well-known and intensely studied phenomenon in condensed matter physics. After the theoretical prediction of Zawadowski and Noizères about the two-channel Kondo (2CK) effect, several successful attempts have been made to experimentally realize the 2CK effect. Usually the 2CK fixed point is not stable in the presence of magnetism as it can break the channel symmetry. But Zhu et al. have recently reported the coexistence of ferromagnetism and 2CK effect in thin films of L10- MnGa and L10- MnAl. The small spin polarization due to the disorder-induced antiparallel aligned between Mn–Mn atoms results in weak channel asymmetry and hence coexistence of 2CK with ferromagnetism. In order to get new insights about the simultaneous presence of magnetism and the 2CK effect, the low temperature magneto-transport properties of the composites containing LaNiO3 (LNO) and CoFe2O4 (CFO) [(1−x)LNO + xCFO; x = 0, 0.10, 0.15, 0.20, 0.25] are studied extensively. For composite with lower percentage of CFO (x = 0.10), spin one channel Kondo effect dominates at low temperature. However, in case of x ≥ 0.15 resistivity below the upturn is governed by orbital 2CK effect which originates from the scattering of conduction electrons with the structural disorders created at the interfaces between the two phases (LNO and CFO). The magnetoresistance and anomalous Hall effect (AHE) are studied in the two composites with x = 0.15 and 0.20 to understand the origin of AHE in systems with structural defects and to unravel the correlation between AHE and 2CK physics. The AHE shows two important phenomena, one is the AHE of the composites with 15 % and 20 % CFO follow scaling behaviour with longitudinal resistivity at high temperature, but shows a deviation around Kondo temperature (TK) and a sudden jump in the temperature variation of anomalous Hall coefficient near TK. These two observations suggest the AHE is strongly influenced by the presence of orbital 2CK effect. The complex impedance spectroscopy (CIS) is a useful tool to correlate the electrical properties with the microstructure and to determine various polarization process present in grain, grain boundaries and electrode-interfaces of polycrystalline materials. In the second part of my thesis, the same compounds (LNO and CFO) are used with changing the composition in such a way that CFO acts as insulating matrix and LNO plays the role of conductive filler [xLNO + (1-x)CFO; x = 0, 0.05, 0.10, 0.15]. The physics of transport and dielectric properties are investigated in detail applying the CIS technique. Adding LNO affects the grain boundary transport in the composites enabling short range hopping of the ions across it
