Spin and valence states of manganese ions in manganese-doped yttrium orthoaluminate
Two paramagnetic charge states of manganese with total electron spin of S=5/2 (Mn 2+) and S=3/2 (Mn 4+) were identified by electron paramagnetic resonance (EPR) method in Mn doped YAlO 3. In addition to the allowed ΔM S =1 spin transitions, low field forbidden ΔM S =2 transitions were observed for b...

4+ and Mn
2+ and
ΔM

=3 transitions for Mn
2+. Relative intensities of forbidden transitions increase with a decrease of temperature and decrease with an increase of Mn concentration. The effect is due to the increase of spin–lattice and/or spin–spin relaxation times at low temperature and the decrease of spin–spin relaxation time at higher dopant concentration.
