This PhD thesis was carried out in the framework of a contract CIFRE between the GREYC laboratory and the company Inphynix. The objective is the study and development of high performance magnetometers, based on search coils and associated transimpedance amplifier with a perspective of simultaneous measurement of both Electric E and Magnetic H fields. The magnetometer specifications were a high bandwidth, a high dynamic range and a small volume occupancy. A theoretical and experimental study of compact search coils dedicated were performed. The spatial resolution for search coils with different geometrical forms was studied. Differential current amplifiers and transimpedance amplifiers optimized for this application were studied especially f...
