Title The study of the giant magnetoresistance effect in the LaNi1-xCoxO3 solid solution
Author Ανδρουλάκης, Ιωάννης Εμμ
Thesis advisor Γιαπιντζάκης, Ιωάννης
Abstract The present work was written in partial fulfillment of the requirements for a Ph.D. degree from the department of Chemistry of the University of Crete, Greece. The work described here was carried out in the Superconducting and Magnetic Materials Laboratory located on the grounds of the Institute of Electronic Structure and Lasers (IESL) at the Foundation for Research and Technology-Hellas (FORTH), under the supervision of Prof. J. Giapintzakis. The thesis is divided in three major parts, namely A, B and C. Part A, consists of three chapters which aim to introduce the reader to the field of magnetoresistance and provide useful information regarding the system in consideration. The third chapter of part A explains in full details the synthesis and characterization of the compounds under investigation. Part B, describes the main experimental findings and provides a consistent picture not only for the magnetoresistance effect but also for a number of physical properties of the solid solution. Finally, part C is a collection of appendices that contain description of experimental techniques used and a report on the growth of LaNi1-xCoxO3 thin films on Si(100) substrates, which have been used for Hall effect studies (chapter 6), using pulsed laser deposition. Every time I try to read a thesis or a book, I usually get lost in the hundreds of references piled up in the last few pages. Thus, I have tried to make every chapter of the present thesis quite self-sufficient from this point of view, in the sense that it contains its own references and it can be read independently. Furthermore, since magnetic units can usually prove to be a real headache for non-expert readers, I have included a table in the very last page, which contains the basic measuring units in the SI and cgs systems of units as well as conversion factors from one to the other.
