Role of Fe magnetic subsystems to form a magnetic spin glass state in RFeTi2O7

The experimental studies on R3+Fe3+Ti2O7 (R=Sm, Gd, Tb, Tm, Dy) magnetic properties evidence the low temperature spin glass state in all compounds. The possibility of rare-earth cation substitution allows the investigation of the role of magnetic iron Fe3+ ions and rare earth R3+ ions subsystems in...

Summary:The experimental studies on R3+Fe3+Ti2O7 (R=Sm, Gd, Tb, Tm, Dy) magnetic properties evidence the low temperature spin glass state in all compounds. The possibility of rare-earth cation substitution allows the investigation of the role of magnetic iron Fe3+ ions and rare earth R3+ ions subsystems in a ground state formation in these oxide compounds. [Display omitted] •The main structural features of LuFeTi2O7 lead to atomic disorder in the distribution of the magnetic Fe3+ ions.•The antiferromagnetic spin system of LuFeTi undergoes a transition from paramagnetic to spin glass magnetic state below TSG=4.5K.•The rare-earth cation substitution of a nonmagnetic ion in RFeTi2O7 system has no major effect on the magnetic ground state.•The disordered distribution of the Fe ions plays the main role in the formation of the spin glass behavior in compounds R3+Fe3+Ti2O7.
