Scientists at NIST have developed a new type of magnetic sensor in a zigzag shape that could be used in various applications. The sensors are made of a thin film of nickel and iron and are 35 micrometers long and 5 micrometers wide. The zigzag design produces many tiny bar magnets oriented at a 45-degree angle, allowing the device to sense magnetic fields more effectively.
The new sensors are expected to produce clearer signals with less electronic noise compared to conventional magnetic sensors. NIST scientists experimented with various dimensions to achieve the desired performance. The project is part of an interdisciplinary effort to design nanoscale sensors with improved detection levels.
The research was published in the Dec. 13, 2004, issue of Applied Physics Letters.
