SHRIMP \u2013 Precision magnetometer<\/h1>\n

Coupling it to a resonator can greatly increase sensitivity to radio-frequency magnetic fields. The study of suitable materials and resonators will make it possible to develop a new class of magnetometers with sensitivities below fT\/\u221aHz\u202fat room temperature.[\/vc_column_text][vc_empty_space][vc_single_image image=”4582″ img_size=”full” qode_css_animation=””][vc_empty_space][vc_column_text]<\/p>\n

How does it work?<\/span><\/h3>\n

[\/vc_column_text][vc_empty_space][vc_column_text]Detecting very weak magnetic fields is an ongoing technological challenge, motivated by the numerous applications of the magnetometers.<\/p>\n

SHRIMP is a magnetometer that incorporates operation at room temperature, high working frequency and ease of implementation, making it useful for a variety of applications. The sensitivity limit of this instrument is the same as or greater than that of the current state-of-the-art magnetometers. The working principle is based on field modulation usually used for the measurement of electron spin resonances. To improve sensitivity, the magnetic material can be coupled to a resonator, such as a microwave mode of a resonant cavity. Numerous realizations of this object can be studied, depending on the applications, ranging from the detection of nuclear magnetic resonance (NMR) signals to fundamental physics.[\/vc_column_text][vc_empty_space][vc_column_text]<\/p>\n
