The authors have synthesized fergusonite-structured La(Nb0·71V0·04Mn0·25)O4samples. The samples, consisting of La3+, Nb5+, V5+, Mn4+and oxygen ions, demonstrated temperature-dependent magnetization that increased with lowering the temperature below ≈200 K, and almost saturated below ≈100 K. At 75 K, the field-dependent magnetization demonstrated sigmoidal curve and reached 3 μB/Mn at 1 T. Such a magnetic behavior can be ascribed to exchange interaction between Mn4+Nb2O11nanoclusters. The Mn4+substitution for the V5+sites of the crystal resulted also in the occupied state above the valence band maximum. |
