Abstract
The results of neutron powder diffraction experiments on a mixed valence ox
ide system CaMn7O12 with a distorted perovskite structure are discussed. Be
low 86 K long-range magnetic ordering of the magnetic moments of Mn3+ and M
n4+ ions was observed. Between 50 and 86 K there are two different ordered
magnetic phases: one ferrimagnetic and the second modulated. Below 50 K bot
h these magnetic phases are modulated. A model of these magnetic structures
is discussed. (C) 1999 Elsevier Science Ltd. All rights reserved.
