V A Streltsov,N Ishizawa,S Kishimoto,

Structure factors for small hydrothermally grown yttrium and holmium orthoferrites, RFeO(3) (R = Y, Ho), were measured with focused synchrotron radiation at wavelengths of 0.70 and 0.84 A using both scintillation and high-speed avalanche photodiode (APD) detectors. Resulting APD Deltarho images showed striking correlations between aspherical electron densities around Fe and rare-earth metals. Approximate high symmetry in the Deltarho images indicates that cations deform the electron density far more strongly than the O atoms. The Ho-Fe magnetic interactions appear to affect the electron density distribution of the Fe atoms and the magnetic phase transitions.
