【 摘 要 】

We study a spin-5/2 antiferromagnetic trimerized chain substance SrMn3P4O14 using neutron powder diffraction experiments. The coplanar spiral magnetic structure appears below T-N1 = 2.2(1) K. Values of several magnetic structure parameters change rapidly at T-N2 = 1.75(5) K, indicating another phase transition, although the magnetic structures above and below T-N2 are qualitatively the same. The spiral magnetic structure can be explained by frustration between nearest-neighbor and next-nearest-neighbor exchange interactions in the trimerized chains.
