説明

Abstract Magnetic susceptibility of a quasi two-dimensional magnet manganese stearate is measured between 0.05 – 80 K by a Hartshorn bridge method. The molar susceptibility follows the Curie-Weiss law in high temperature range: χ m = 4.8/ (T + 40) (emu/mol). A transition to weak-ferromagnetic ordered state occurs at about 0.5 K, where the susceptibility maximum is observed. χ H + σ measured by the use of SQUID magnetometer indicates the appearance of spontaneous magnetization below 0.5 K. A preliminary study of a monolayer structure gives a shift of the maximum of χ H + σ to about 0.3 K.
