摘要: Magnetization and differential susceptibility of manganese tartrate dihydrate were measured in a single crystal from room temperature down to 0.4 K the presence magnetic fields up 70 kOe. Nearly antiferromagnetic order occurs below TN = 1.83 K, with spins oriented close c axis. Sharp peaks remanent magnetization plane perpendicular axis suggest weak ferromagnetic structure canting angle 0.6°. The phase diagram was determined. exchange anisotropy field obtained respectively as HE 19.4 kOe HA 0.6
