Molecular Nanomagnets-towards molecular spintronics
Molecular nanomagnets, often called single-molecule magnets, have attracted much interest in recent years both from experimental and theoretical point of view. These systems are organometallic clusters characterized by a large spin ground state with a predominant uniaxial anisotropy. The quantum nature of these systems makes them very appealing for phenomena occurring on the mesoscopic scale, […]
Challenges for semiconductor spintronics
High-volume information-processing and communications devices are at present based on semiconductor devices, whereas information-storage devices rely on multilayers of magnetic metals and insulators. Switching within information-processing devices is performed by the controlled motion of small pools of charge, whereas in the magnetic storage devices information storage and retrieval is performed by reorienting magnetic domains (although […]
Spintronics-Fundamentals and applications
Spintronics, or spin electronics, involves the study of active control and manipulation of spin degrees of freedom in solid-state systems. This article reviews the current status of this subject, including both recent advances and well-established results. The primary focus is on the basic physical principles underlying the generation of carrier spin polarization, spin dynamics, and […]
