Abstract

Single-crystalline Li₄Mn₅O₁₂ nanosticks were prepared by a simple method of adding MnSO₄ to molten LiNO ₃ and NaNO₃. FESEM and HRTEM investigations revealed that two-dimensional Li₄Mn₅O₁₂ nanosticks were generated in large quantity. The results of dc and ac magnetization as well as magnetic hysteresis measurements suggest spin-glass-like behavior at 9.8 K. Furthermore, an exchange-bias effect is observed over the material in applied magnetic field of H ≤ 5 T.
