Structural and magnetic properties of “expanded” Mn deposited on (111) oriented fcc 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 Å−1 along six equivalent [112̄] 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 TN⩾20 K. The magnetic and structural data are consistent with understanding the expanded phase as trigonally distorted α-Mn.
