Abstract:	摘要： The effects of size on the magnetic properties of HoMn 2 O 5 nanorods were studied. Nanorods were made with five radial (<;L C >) × axial lengths - 24(7) nm × 49(19) nm, 33(14) nm × 66(25) nm, 31(9) nm × 69(25) nm, 54(13) nm × 95(27) nm, and 114(52) nm × 409(109) nm. The axial directions of the nanorod were parallel to the c-axis of the crystals. All samples crystallized with orthorhombic Pbam symmetry with no phase change between 15 and 300 K. Upon cooling, only the sample with <;L C > = 409 nm exhibited incommensurate and incommensurate-to-commensurate antiferromagnetic transitions at 43 and 38 K, respectively. No sample yielded an obvious hysteresis loop at 2 K. Measurements of magnetic susceptibility reveal that the critical range of sizes for magnetic ordering in HoMn 2 O 5 is between <;L C > = 95 and 409 nm. 其他題名： TMAG 出版者： New York: IEEE 出版日期： 2014-11 出處： IEEE transactions on magnetics, 2014-11, Vol.50 (11), p.1-3 資源來源： IEEE Xplore Digital Library 版權： Copyright The Institute of Electrical and Electronics Engineers, Inc.
