Marine CSEM is a new technique for detection of deep target hydrocarbons. Aluminum EM antenna was developed, and nanostructured N i Z n magnetic feeders were used to increase the field strength from EM antenna for deep hydrocarbons. The doping of N i 2+ was aimed at the optimization of initial permeability and magnetic losses. Ni 0.5+ x Z n 0.5‐ x F e 2 O 4 ( x = 0.3) samples sintered at 950°C presented highest initial permeability (106.23) and low magnetic loss (0.0002) as compared to other samples. Due to better magnetic properties, N i 0.5+ x Z n 0.5‐x F e 2 O 4 ( x = 0.3) samples were used as magnetic feeders for EM antenna. Magnitude of EM waves from the antenna increased up to 186%.
