Schematic view of apparatus developed to measure magnetic grain alignment under low-temperature conditions between T = 100 K and 10 K (Uyeda et al., 2001, 2004c). He gas is used as the dispersing medium. A set of Helmholz coils produces a homogeneous magnetic field in a spherical area of 100 mm in diameter; the sample suspension is included in this area. Alignment of graphite grain at T = 110 K was recently performed using this setup (Uyeda et al., 2004c).
