Ferrimagnetic perovskites

Phases containing the smaller lanthanoids, Dy, Ho, Er, Tm, Yb and Lu, transform to a ferrimagnetic state at approximately 7 240K for all compounds. This is due to a charge disproportionation between the transition metal cations  [Pg.236]

According to the Curie-Weiss law the theoretically predicted paramagnetic moment for a d d ferrimagnetic system should be around 4.90 pg rather than the observed Pe of 2.81 pg. However, the analysis of reported magnetic susceptibility data for a variety of ferrimagnetic double-perovskites [6,10-13] shows that the observed paramagnetic... [Pg.15]

The solid solution Sr2(FeMOjjWi JOs also has the perovskite structure and the end-member Sr2Fe +Mo +Og is ferrimagnetically ordered at room temperature with a field of 315 kG [119]. Appreciable Fe " " content is not found until above 70% Sr2Fe +W 06 in composition because of appreciable reduction to W. ... [Pg.273]

The orthoferrites, RFeOa, where R is yttrium or a rare-earth element have a structure based on a distorted perovskite lattice with only one iron environment. Most of them possess weak ferrimagnetic character as a result of spin canting from the ideal two-sublattice antiferromagnetic ordering. [Pg.273]
