Due to a nuer of unique properties, nanoferrites are considered among the most emerging materials for the manufacturing of microwave devices. In past few years, different elemental compositions of nanoferrites were fabried for this purpose. In our work, magnesium-doped lithium ferrites (Li2−xMgxFe2O4.5−δ, where x = 0.0 to 1.0) were synthesized by using co-precipitation method in

Four-dimensional inversion of resistivity monitoring data …

The resistivity differences are the differences between the two logarithmic resistivity values at two subsequent time steps, T2 and T3, and T7 and T8. In theory, as the TD regularization parameter is set smaller, the smoothness constraint in the time domain makes a smaller contribution to the inversion; as a result, the TD model roughness, that is, resistivity changes along the time axis
