Abstract
Resonant and nonresonant x-ray scattering studies on HoFe 3(BO3)4 reveal competing magnetic ordering of Ho and Fe moments. Temperature and x-ray polarization dependent measurements employed at the Ho L3 edge directly reveal a spiral spin order of the induced Ho moments in the ab plane propagating along the c axis, a screw-type magnetic structure. At about 22.5 K the Fe spins are observed to rotate within the basal plane inducing spontaneous electric polarization, P. Components of P in the basal plane and along the c axis can be scaled with the separated magnetic x-ray scattering intensities of the Fe and Ho magnetic sublattices, respectively. © 2012 American Physical Society.
