Martinelli A., Ferretti M., Cimberle M. R., Ritter C. The crystal and magnetic structure of Ti-substituted LaCrO3. In: Materials Research Bulletin, vol. 46 pp. 190 - 193. Elsevier, 2011.
The crystal and magnetic structures of LaCrO3 and La(Cr0.90Ti0.10)O3 have been investigated between 5 and 350 K by means of neutron powder diffraction. Both compounds are characterized by an antiferromagnetic Gx-type ordering at low temperature. Despite the mixed valence induced by Ti-substitution leading to the occurrence of the Jahn-Teller species Cr2+, no evidence for long range ferromagnetism can be detected. On account of a miscibility gap, a higher degree of Ti-substitution at the Cr site can not be achieved.
