New Method to Estimate Magnetic Hamiltonian Parameters from Spin Structure Images
Written by AZoMDec 17 2020
Spintronics is actively studied to overcome the drawbacks of the integration level of silicon semiconductors that are in use at present and to develop ultra-low-power and high-performance next-generation semiconductors.
