Researchers Develop Compact Spin-Torque Microwave Detector with Enhanced Sensitivity
A team of researchers from China, Italy, and Saudi Arabia has developed a compact spin-torque microwave detector. This innovative device utilizes a magnetoelectric antenna composed of an iron gallium boron/aluminium oxide magnetostrictive top electrode, an aluminium nitride piezoelectric layer, and a molybdenum electrode. The detector boasts a sensitivity to microwave signals exceeding 90 kV W⁻¹ and operates within a range of 510 MHz to 650 MHz. The device's small footprint of 0.4 mm² and its ability to integrate multiple magnetic tunnel junctions enhance its sensitivity, making it a significant advancement in microwave detection technology.
