Co-occurrence of Superparamagnetism and Anomalous Hall Effect in Highly Reduced Cobalt-Doped RutileTiO2−δFilms

Co-occurrence of Superparamagnetism and Anomalous Hall Effect in Doped Rutile TiO2-δ Films

We report a detailed magnetic and structural analysis of highly reduced Co d displaying an anomalous Hall effect (AHE). The temperature and field dependen transmission electron microscopy clearly establish the presence of nano-sized s clusters of ~8–10 nm size in the films at the interface. The co-occurrence of s AHE raises questions regarding the use of the AHE as a test of the intrinsic natu ...

Extraordinary Hall effect and ferromagnetism in Fe-doped reduced rutile

Prospect of quantum anomalous Hall and quantum spin Hall effect in doped kagome lattice Mott insulators

Electronic states with non-trivial topology host a number of novel phenomena with potential for revolutionizing information technology. The quantum anomalous Hall effect provides spin-polarized dissipation-free transport of electrons, while the quantum spin Hall effect in combination with superconductivity has been proposed as the basis for realizing decoherence-free quantum computing. We intro...

Anomalous Hall effect

We present a review of experimental and theoretical studies of the anomalous Hall effect (AHE), focusing on recent developments that have provided a more complete framework for understanding this subtle phenomenon and have, in many instances, replaced controversy by clarity. Synergy between experimental and theoretical work, both playing a crucial role, has been at the heart of these advances. ...
