Magnetic field induced discontinuous spin reorientation in ErFeO₃ single crystal

Origin of the magnetization and compensation temperature in rare-earth orthoferrites and orthochromates

“…(2) renders a picture in which the magnetic ordering of the M spins and the oxygen octahedral tilting work together to create an effective magnetic field, B R eff , acting on the rare-earth sublattice and given by 31,33,35 ) the net magnetization vanishes at a specific compensation temperature, T comp . This effect has been attributed to the fact that, below a certain temperature, the R ions acquire a magnetization that is opposite to that of the Fe/Cr sublattice and grows faster than the one of the B ions when further decreasing the temperature, 26,27 as suggested by the relatively large paramagnetic susceptibility of the R spins. 11,12 The two magnetizations cancel each other at T comp , and further decreasing the temperature leads to a reversal of the magnetization sign, as the ground state magnetization of the R sublattice is larger than that of the M sublattice.…”

Investigation of magnetic property of GdFeO3 single crystal grown in air by optical floating zone technique

“…However our measurement of temperature dependent H C shows a significant anomaly. The occurrence of Morin transition (which could have been a possibility) is ruled out in this system by several earlier reports on ortho-ferrite [29,30]. So at present the reason behind the lowering in the H C is not understood.…”

Effect of Fe doping on the magnetic ordering temperature of ErMnO3

“…Among these interactions, the Fe 3þ -Fe 3þ superexchange interactions is the dominant one with Fe 3þ -O-Fe 3þ bond angle close to 144 . 25 In the present case, Fe doing on Mn site in EMO reduces the lattice parameters c drastically from 11.3965 Å to 7.494 Å (which is b-axis in EFMO according to Pnma nomenclature). It leads to the distortion in the MnO 5 polyhedra to MnO 6 octahedra in EMO, as seen in Fig.…”
