  Ultrasnsitive multi-mode electron spin resonance spectroscopy in the
$SrLaAlO_4$ dielectric resonator at $20~mK$ reveals ferromagnetic states of
$Mn^{4+}$ impurity ion. The formation of ferromagnetic states in the $MnO_6$
complex implies to oxygen deficiency of this multi-valence $Mn^{4+}$ ion.
Experiment results supports that an intricate electronic hybridization in
$MnO_6$ structural instability is related to Pseudo Jahn-Teller effect.
Measured dipolar hyperfine structure parameter of nucleus is
$P_{\scriptscriptstyle\parallel} =-3.7\times 10^{-4}~cm^{-1}$. Mean inverse
third power of the electron distance is $\langle r_q^{-3}\rangle=3.325~a.u.$
assuming nuclear electric quadruple moment $Q=+0.33(1)~barn$. In such a state,
giant g-factor is observed due to magneto (ferromagnetic) impedance taking in
to account a two-level system on the adiabatic-potential-energy-surface. The
spins exhibited parity is opposite in the interaction of
highest-occupied-molecular-orbital and lowest-unoccupied-molecular-orbital
coupling.
