Webb29 okt. 2024 · Ultrasensitive magnetic field sensors based on magnetoelectric (ME) structures have many applications in bio-magnetic sensors and magnetoencephalography (MEG) scanners. Enhance the sensitivity,... WebbGiant magnetostrictive materials such as Terfenol-D and Galfenol are used to design actuators and sensors, converting magnetic input into a mechanical response, or conversely, mechanical input into a magnetic signal. Under standard operating conditions, these materials are subjected to stress. It is therefore important to be able to measure, … Webb10 apr. 2024 · Decreasing the anisotropy or increasing the initial susceptibility implies that the MNPs can reach the saturated state at lower magnetic fields [58]. Therefore, for the y - or z -axis that have a magnetic field gradient half of the one in x -axis, increasing the size would be beneficial for improving the spatio-thermal resolution. helia hosseini ucla
