We illustrate neutrino mass and magnetic moment along with dark matter phenomenology in a Type-III radiative scenario. To achieve this, we extend the Standard Model with three vector-like fermion triplets and two inert doublets, which can provide a suitable framework for studying the above phenomenological aspects. The inert scalars contribute to the total relic density of dark matter in the universe. The neutrino aspects are realized at one-loop level with magnetic moment obtained through charged scalars, while neutrino mass gets contribution from charged and neutral scalars. Taking inert scalar upto 2 TeV and triplet fermion mass in a few TeV range, we obtain a common parameter space, compatible with experimental limits associated with both neutrino and dark matter sectors. Finally, we demonstrate that the model is able to provide neutrino magnetic moments in a wide range from 10−12µB to 10−10µB, meeting the bounds of various experiments such as Super-K, TEXONO, Borexino and XENONnT.
