Static and Resonant Properties and Magnetic Phase Diagram of LiMn2TeO6

Physical properties of the mixed-valent tellurate of lithium and manganese, LiMn2TeO6, were investigated in measurements of ac and dc magnetic susceptibility chi, magnetization M, specific heat C-p, electron spin resonance (ESR), and nuclear magnetic resonance (NMR) in the temperature range 2-300 K under magnetic field up to 9 T. The title compound orders magnetically in two steps at T-1 = 20 K and T-2 = 13 K. The intermediate phase at T-2 < T < T-1 is fully suppressed by magnetic field mu H-0 of about 4 T. Besides magnetic phases transitions firmly established in static measurements, relaxation-type phenomena were observed well above magnetic ordering temperature in resonant measurements.
