Magnetism and Transport Phenomena in Spin-Charge Coupled Systems on Frustrated Lattices

Abstract

The series "Springer Theses" brings together a selection of the very best Ph.D. theses from around the world and across the physical sciences. Nominated and endorsed by two recognized specialists, each published volume has been selected for its scientific excellence and the high impact of its contents for the pertinent field of research. For greater accessibility to non-specialists, the published versions include an extended introduction, as well as a foreword by the student's supervisor explaining the special relevance of the work for the field. As a whole, the series will provide a valuable resource both for newcomers to the research fields described, and for other scientists seeking detailed background information on special questions. Finally, it provides an accredited documentation of the valuable contributions made by today's younger generation of scientists.Theses are accepted into the series by invited nomination only and must fulfill all of the following criteria • They must be written in good English.• The topic should fall within the confines of Chemistry, Physics, Earth Sciences, Engineering and related interdisciplinary fields such as Materials, Nanoscience, Chemical Engineering,

Metal-Insulator Transition and Band Magnetism in the Spin-$1/2$ Falicov-Kimball Model on A Triangular Lattice with External Magnetic Field

“…Therefore in the present article we would like to explore the ground state properties of the spin-dependent FKM on a triangular lattice with finite external magnetic field which affects the orbital (through Pierels substitution) and spin (through Zeeman coupling or effective Lande g−factor) degrees of freedom of the itinerant d−electrons. These results will be very close to the recent theoretical and experimental findings on the triangular lattice [44,45,46,47]. Many other novel aspects of the correlated electron systems like non-trivial topology in band structure, charge, orbital and magnetic ordered configurations and their metallic or insulating nature are also expected to be uncovered.…”

Tuned electronic and magnetic properties in 3d transition metal doped VCl3 monolayer: a first-principles study

“…Intriguingly, in SGS materials, no threshold energy is required to excite electrons from the valence band to the conduction band, and the excited carriers can be fully spin-polarized [3]. Moreover, another type of newly introduced spintronic materials is the Dirac half-metals (DHM), which are a subclass of half-metals characterized by semiconducting character in one of the spin channels and metallic character with the presence of a Dirac cone in the other channel [7,8]. DHM materials offer very interesting physical properties such as ballistic charge transport, topological phases, linear band dispersion, and extremely high carrier mobility [9,10] making them very promising materials for spintronic applications.…”
