A new detection method using magnetization generated at triggered radiativeemission of neutrino pairs (RENP), $ |e \rangle \rightarrow | g \rangle +\gamma + \sum_{ij}\nu_i \bar{\nu}_j $ (atomic de-transition from state $|e\rangle $ to state $|g \rangle$ emitting sum of neutrino pairs$\sum_{ij}\nu_i\bar{\nu}_j$ accompanied by a photon $\gamma$), is investigatedin order to determine unknown neutrino properties; absolute neutrino masses of$\nu_i$ and Majorana/Dirac distinction. Magnetization associated with RENPevents has parity violating component intrinsic to weak interaction enforced bycrystal field effect in solids, and greatly helps background rejection ofquantum electrodynamic (QED) origin even when these backgrounds are amplified.In proposed experiments we prepare a coherently excited body of trivalentlanthanoid ions, Er$^{3+}$ (a best candidate ion so far found), doped in atransparent dielectric crystal. The magnetic moment $\mu \langle\vec{S}\cdot\vec{k} \rangle/k $ arising from generated electron spin $\vec{S}$parallel to trigger photon direction $\vec{k}/k$ is parity odd, and is absentin QED processes. The generated magnetic field of order nano gauss is stored incrystals long after pair emission event till spin relaxation time. An improvedcalculation method of coherent rate and angular distribution of magnetizationis developed in order to incorporate finite size effect of crystal targetbeyond the infinite size limit in previous calculations.
