A new detection method using magnetization generated at triggered radiative emission of neutrino pairs,(which is the atomic deexcitation from stateto statewhile emitting the sum of neutrino pairsaccompanied by a photon), is investigated in order to determine unknown neutrino properties: the absolute neutrino masses ofand Majorana/Dirac distinction. Magnetization associated with radiative emission of neutrino pair events has a parity violating component intrinsic to weak interaction enforced by the crystal field effect in solids, and greatly helps background rejection of QED origin even when these backgrounds are amplified. In proposed experiments we prepare a coherently excited body of trivalent lanthanoid ions,(a best candidate ion so far found), doped in a transparent dielectric crystal. The magnetic momentarising from generated electron spinparallel to trigger photon directionis parity odd, and is absent in QED processes. The generated magnetic field of order nano-Gauss is stored in crystals long after pair emission event till spin relaxation time. An improved calculation method of coherent rate and angular distribution of magnetization is developed in order to incorporate finite size effect of crystal target beyond the infinite size limit in previous calculations.
