Design and fabrication of piezoelectric MEMS SAW pressure sensors

Introduction Micro-Electro-Mechanical Systems (MEMS) pressure sensors have increasingly become critical components in various applications, especially in environments characterized by extreme conditions such as high temperatures, strong radiation, corrosive media, and high pressures. These harsh environments are commonly found in industries such as aerospace, automotive, oil and gas, and nuclear power generation. The unique challenge presented […]

Magnetic heterostructures and exchange anisotropy

Introduction Ferromagnetism is a form of magnetism where materials exhibit permanent magnetization and strong attraction to external magnetic fields, being the strongest type compared to paramagnetism, diamagnetism, and antiferromagnetism. These materials possess magnetic hysteresis, meaning they retain magnetic alignment even after the external magnetic field is removed, with the level of retained magnetization known as […]
