Electromagnetic signals in deep reservoir are very weak so that it is difficult to predict about the presence of hydrocarbon in seabed logging (SBL) environment. In the present work, Mn 0.8 Zn 0.2 Fe 2 O 4 nanoferrites were prepared by a sol–gel technique at different sintering temperatures of 450°C, 650°C and 850°C to increase the strength of electromagnetic (EM) antenna...
