Anisotropy of magnetic properties in LaMnO3 single crystals

The magnetization M and the magnetic susceptibility X of single crystals LaMnO 3 have been studied as functions of external magnetic field H (up to 50kOe), angle Φ between the field direction and a crystallographic axis in the LaMnO 3 lattice, and temperature T. At T = 2 K the spontaneous magnetization M 0 and the magnetic susceptibility along the main directions a, b, c in the orthorhombic lattice (P nma ) of LaMnO 3 are 6.5 emu/g and X b X c 2X a ≅0.00013cm 3 /g, respectively. The results support a canted A a F b ,-type magnetic structure, however the spin flop transition at H < 50 kOe was not observed.
