Magnetic excitations in a frustrated Cairo pentagon lattice.

We propose to measure the high energy magnon spectrum of Bi2Fe4O9 in order to finalize a spin wave model and to classify this compound within the theoretical phase diagram of...本研究提出对Bi₂Fe₄O₉的高能磁振子（magnon）谱进行测量，以期完善自旋波模型，并将该化合物归类于……的理论相图框架内。
