| dc.description.abstract | The structural and magnetic properties of (Tb1-xCex)MnO3 have been investigated. The presence of Griffith's phase has been confirmed from the AC susceptibility study of the materials. The observed Griffith phase in (Tb1-xCex)MnO3 is attributed to the exchange interaction between Mn3+/Mn2+ ions. Chemical analysis by X-ray photo-emission spectroscopy has shown the presence of mix valence state of Mn and oxygen vacancy in the materials. At low temperatures, the materials also show existence of exchange bias in field cooled condition which changes with Ce content. Jahn-Teller distortion and oxygen vacancy are found to dominate in these systems to change the Mn–O–Mn bond angle which in turn induce canted antiferromagnetism (AFM) in this system. The canted AFM plays an important role in getting the exchange bias effect. | en_US |
