Magnetic Signature Duplicator

This book aims then to describe in a comprehensible way efforts made over centuries of measuring and understanding the magnetic declination. The book also highlights some important characteristics of the Earth’s magnetic field thanks to the declination measurements. Some applications and societal implications are also underlined.

This book explicates the optical controls of antiferromagnetic spins by intense terahertz (THz) electromagnetic waves. The book comprises two key components: (1) the experimental demonstration of the enhancement of a THz magnetic field using a split-ring resonator (SRR) and (2) the control of the direction of magnetization by using the enhanced THz magnetic field to break the symmetry of optically-induced phase transition. These make up the first step leading to future spintronics devices.

This book describes several aspects of transcranial magnetic stimulation (TMS) in neuropsychiatry: inhibitory and excitatory mechanisms of the human brain, the use of TMS in the research and treatment of cognitive disorders, various aspects of TMS application aimed at the cerebellum, its effects on impulsivity in attention deficit hyperactivity disorder and borderline personality disorder, its effects in the treatment of tinnitus and obsessive-compulsive disorder, pain and chronic headache, and finally the safety of TMS for staff.

This thesis presents the first ever measurement of the noise emitted by magnetic monopoles and the development of an exquisitely sensitive magnetic-field-noise spectrometer based on a superconducting quantum interference device (SQUID) that enabled it. Magnetic monopoles are highly elusive elementary particles exhibiting quantized magnetic charge.

This book presents an overview of the different types of new magnetic materials and hybrid structures that exhibit different magnetic phenomena and interesting properties. The reported materials are studied theoretically and experimentally, which are the building blocks of all technological innovations. The chapters of the book provide a key description of magnetic materials.

This book presents a basic overview of magnetic skyrmions along with current research on magnetic skyrmions, emphasizing formation mechanisms and materials design strategies. This book is suitable for an interdisciplinary audience of undergraduates, graduates, engineers, scientists, and researchers in the development of the next generation of spintronic devices.

The scope of this work is to provide an extensive experimental investigation of ferrotoroidicity, the most recently established type of ferroic order that is based on the uniform unit-cell-sized alignment of magnetic whirls. This is achieved by transferring basic spin configurations pertinent for the emergence of toroidal order to mesoscopic length scales. An engineering of and access to the system's magnetic degrees of freedom is made possible by using nanomagnetic arrays as model systems. The work reveals microscopic and macroscopic aspects of toroidally ordered matter beyond the reach of natural materials.
