Abstract

This paper discusses exchange splitting in the spectra of Er 3+ introduced as a spectroscopic probe in rare-earth ferroborates RFe 3 (BO 3 ) 4 (R=Y,Er,Tb,Gd). The temperatures of magnetic ordering are determined [38±1 K for YFe 3 (BO 3 ) 4 , 39±1 K for ErFe 3 (BO 3 ) 4 , 41±1 K for TbFe 3 (BO 3 ) 4 , 37±1 K for GdFe 3 (BO 3 ) 4 ] and the spin-reorientation transition in GdFe 3 (BO 3 ) 4 :T R =7.5±0.5 K. Based on a comparison of the Er 3+ spectra in GdFe 3 (BO 3 ) 4 , the magnetic structure of which is known, and in other ferroborates, a conclusion is made concerning the orientation of the magnetic moments of iron M Fe in the magnetically ordered state: M Fe ⊥ c for yttrium and erbium ferroborates, and M Fe ∥c for terbium ferroborate.
