We investigate doped materials electronic processes, structure, and magnetic
properties. Magnetic resonance esr indicates (Fe,Mn)$_{\mathrm{E-6}}$MgO,
Fe$_{\mathrm{\% }}$NbO stability is by vacancy $\emptyset $ polarized free
electrons e$^{\mathrm{-}}_{\mathrm{P}}$. We describe stability by two
energy X-Ray diffraction 2D XRD, SLAC:SSRL BL2.1 Si(111) crystal detected
resonance enhanced scans: E$\to $Fe-Mn K-edges, and E$+\Delta $E obtain
Bragg: I(E)$_{\mathrm{\nu =0,1,}}$ vs. Q,Q*\underline {\textless }60/nm,
sideband structure $\nu $q$_{\mathrm{PLD}}$ (q$_{\mathrm{PLD}}$\textless
0.1/nm) and followed by exited states relaxation coherent stimulated
absorption/emission, Compton: I*(E)Q aligned vs. $\Delta
