Abstract
(English)
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.
