Abstract

Single crystals of Bi 3Mn 1.9Te 1.1O 11 were prepared from NaClKCl flux. This compound adopts KSbO 3-type crystal structure as evidenced by electron and single crystal X-ray diffraction analysis. The three-dimensional channel structure is formed by corner-sharing octahedral (Mn 0.63Te 0.37) 2O 10 dimers and two identical (Bi1) 4(Bi2) 2 interpenetrating lattices. The intra-dimer Mn/Te-Mn/Te distances in Bi 3Mn 1.9Te 1.1O 11 are short and are consistent with weak metal-metal interactions. The mixed oxidation state of manganese and the edge-sharing octahedral features are confirmed by X-ray near edge absorption spectroscopy measurements, which indicate Bi 3(Mn III 1.1Mn IV 0.8)Te VI 1.1O 11 with 57.7% Mn 3 and 42.3% Mn 4. The partial substitution of Te for Mn perturbs long-range magnetic interactions, thereby destroying the ferromagnetic ordering found in Bi 3Mn 3O 11 (T C=150 K).
