The search for new non-volatile memory technologies is a very intensive research area today. A promising candidate is magnetic RAM (MRAM), and several academic groups and electronics companies are using Atomistix ToolKit (ATK) from QuantumWise for different stages in the analysis of new materials for MRAM structures. ATK is a very popular tool within the entire general area of spintronics, for studies of various novel applications and devices where the information is carried not by the electron charge, but by its spin.
