Context of project
Nowadays, our society has to deal with an enormous and ever increasing amount of data. Although, this data revolution has many positives to take for our lives, there are concerns regarding the sustainability of new technologies to fulfill the need of larger capabilities for data storage and rapid exchange of information. We were invited to write a review/perspective article to cover this very topic, the efforts towards the development of energy-efficient storage devices. We recapitulated part of the main directions of the last years of research in condensed matter in storage mechanisms and energy harvesting. Abstract of our review The current data revolution has, in part, been enabled by decades of research into magnetism and spin phenomena. For example, milestones such as the observation of giant magnetoresistance, and the resulting development of the spin-valve read head, continue to motivate device research. However, the ever-growing need for higher data processing speeds and larger data storage capabilities has caused a significant increase in energy consumption and environmental concerns. Ongoing research and development in spintronics should therefore reduce energy consumption while increasing information processing capabilities. Here, we provide an overview of the current status of research and technology developments in data storage and spin-mediated energy harvesting in relation to energy-efficient technologies. We give our perspective on the advantages and outstanding issues for various data-storage concepts, and energy conversion mechanisms enabled by spin.
