I use Unified Spinor Fields (USF), to discuss the creation of magnetic monopoles during preinflation, as excitations of the quantum vacuum coming from a condensate of massive charged vector bosons. For a primordial universe with total energy M-p, and for magnetic monopoles created with a total Planck magnetic charge q(M) = q(P) = +/- e/root alpha and a total mass m(M), it is obtained after quantisation of the action that the fine-structure constant is given by: alpha = 5/6 (1 - 16 m(M)/5 M-p) (e/q(M))(2). If these magnetic monopoles were with total magnetic charge q(M) = +/- e and a small mass m = m(M)/n, there would be a large number of small quantum magnetic monopoles which could be candidates to explain the presence of dark matter with a 30.97% of the energy in the primordial universe at the Planck era. The case of milli-magnetically charged particles is also analysed. We demonstrate that magnetic monopoles (MM) with masses less than 3.6 x 10(3) GeV, can exist with a very small charges of up to 10(-14) e, which are quantities of interest for searches to be performed in the ATLAS and MoEDAL experiments.
