概要
- 論文の詳細を見る
(La_<1-x>Y_x)Mn_4Al_8 (0≤x≤1) is a very unique itinerant electron system, in which the spin pseudogap can be controlled continuously and nearly uniformly in a wide range of the gap width from Δ≃250 to 500K by the anisotropic volume shrinkage induced by the chemical pressure. The hydrostatic pressure on LaMn_4Al_8 also increases Δ but tends to fill the gap. The strong and anisotropic volume dependence of Δ strongly supports the idea that the origin of the gap formation is associated with the one-dimensional geometry of the Mn spin arrangement.
