| 概要 | Magnetic susceptibility and transport properties of an itinerant helimagnet FeAs are studied in single-crystalline samples of this binary compound. A kink due to the magnetic transition is observed in the temperature dependences of both the susceptibility and the resistivity. The Hall coefficient shows a reentrant sign change with temperature, signifying a complicated competition between multiple bands. In the helical ordered state, we found an unexpected formation of some anisotropic anti ferromagnetic domains. which is reflected in a spin-glass like behavior observed only in the c-axis magnetic susceptibility. |
