Magneto crystalline anisotropy performed on oriented TbMn0.98Fe0.02O3 single crystal by magnetization and AC susceptibility measurements. Our measurements revealed magneto crystalline anisotropy with respect to main crystallographic axes. The paramagnetic Weiss temp. spans a broad range of values which can indicate the strong magnetocrystalline anisotropy in the system. The magnetic phase transitions at TN, Tlock and T1 are connected with anomalies in magnetization and AC susceptibility measurements performed along b-axis. Hysteresis loops measurements indicate suppression of Tb3+ ordering in high magnetic field which depends oN crystal orientation. In respect to iron doping our results resemble and extend results obtained on powdered crystals. Iron doping shifts both TN and Tlock to lower temp., antiferromagnetic JAF interaction in acplane decreases leaving barely changed ferromagnetic interaction JF. The critical field of the field induced phase transition increases with iron doping.
