Abstract
The need for reconfigurable and energy-efficient logic systems in modern computing has led to growing interest in spintronic devices. Spin-orbit-torque magnetic tunnel junctions (SOT MTJs) present an effective solution, enabling fast and low-power logic operations without requiring external magnetic fields. In this work, we introduce a reconfigurable SOT MTJ device capable of performing seven distinct Boolean logic operations: and, or, nand, nor, not, xor, and xnor. The device leverages the unique properties of spin-orbit torque to dynamically switch between two circuit configurations, with the input voltages controlling the logic gate function. Experimental results demonstrate the successful implementation of all seven gates, validating the device’s efficiency and versatility. This work highlights the potential of SOT MTJs for scalable, low-power spintronic logic systems, offering a promising path for next-generation reconfigurable computing applications.
