摘要：

Structural and magnetic properties of ''expanded'' Mn deposited on(lll) oriented fee noble metals were studied with single-crystal x-ray diffraction and exchange bias measurements. A single peak corresponding to this phase was found at momentum transfer q = 2.86 Angstrom(-1) along six equivalent [11 (2) over bar] directions of the noble metal substrate. Magnetic hysteresis of the field cooled Fe/Mn bilayers exhibited a characteristic shift along the field axis, indicating antiferromagnetic order in the expanded Mn with T-N greater than or equal to 20 K. The magnetic and structural data are consistent with understanding the expanded phase as trigonally distorted alpha-Mn. (C) 1998 American Institute of Physics. [S0021-8979(98)37511-8].
