Composition-dependent Magnetic Properties of Si1-xMnx (0.1 < x < 0.9) Single Crystals
Journal of Magnetics, Volume 15, Number 2, 30 Jun 2010, Pages 56-60
Abstract
In this study, we investigated the optical, magnetic, and electrical transport properties of Si1-xMnx (0.1 < x < 0.9) single crystals grown by the vertical Bridgman method. The alloys with a Mn concentration of up to 64% demonstrated weak ferromagnetic ordering around TC = 30 K. The Si0.25Mn0.75 and Si0.18Mn0.82 alloys showed weak ferromagnetic ordering at 70 K and antiferromagnetic ordering at 104 K, as confirmed by magnetization, neutron diffraction, and transport studies.
Keywords: SiMn; magnetic transition; weak ferromagnetic
