Are spintronic devices energy efficient?

The current surge in data generation necessitates devices that can store and analyze data in an energy efficient way. This Review summarizes and discusses developments on the use of spintronic devices for energy-efficient data storage and logic applications, and energy harvesting based on spin.

Can spin state regulation improve energy storage performance?

This review aims to elucidate the advantages of controlling the spin states of metal centers to enhance energy storage performance and highlights recent progress in employing spin state regulation in electrochemical energy storage. Additionally, it covers the various characterization techniques used to determine spin states.

Why do spintronics devices use less power?

On contrast, less energy is needed to switch the spin states from 0 to 1 or vice versa, so spintronics devices use less power. Comparing with conventional electronics, using a single chip to perform many functions makes the device faster and small.

Why are spintronic devices so popular?

Though the concept of electron spin was realized in the 1920s only, challenges in fabrication technology have hindered the development of spintronic devices and circuits. Spintronic devices hold supremacy in terms of their non-volatility, scalability, ease to read and write, and high endurance over the CMOS devices.

Can spin information be used for energy harvesting?

In terms of energy harvesting with spin information, perhaps the most revolutionary concept in the last years has been the advent of the spin Seebeck effect and anomalous Nernst effect with already on-going commercial thermoelectric device devel-opments.

Why is spintronics not energy-dependent?

In spintronics, the spin of electron is not energy-dependent (i.e., nonvolatile, permanent magnetism) which means that the information remains fixed if power is cutoff. Also, the capacitors in conventional electronics are constantly recharged (consume more energy) due to charge is leaking out .
