“…In RFe 3 (BO 3 ) 4 , the magnitude of the electric polarization by the R 3+ and Fe 3+ ions are locally determined by the magnetic moments [22,23]. In the case of NdFe 3 (BO 3 ) 4 the existence of the in-plane anisotropy favoring order along the a axis by the Nd 3+ and/or Fe 3+ ions is a key to the emergence of the multiferroicity.…”

“…The multiferroic mechanism of RFe 3 (BO 3 ) 4 is the spindependent metal-ligand hybridization model [22,23] where the relation between the electric polarization and the magnetic moment is locally determined by the symmetry of O 2− ions around the magnetic ion. In a collinear magnetic structure the local magnetic anisotropy is a casting vote in the determination of the magnetic structure, and, consequently, in the determination of the electric polarization as well.…”

“…Тригональные редкоземельные оксибораты RMe 3 (BO 3 ) 4 (где R = Y, La−Lu; M = Fe, Al, Cr, Ga, Sc) в последние годы интенсивно исследуются многими российскими и зарубежными научными группами [1][2][3][4][5][6][7]. В случае боратов с двумя магнитными подсистемами (ферробораты RFe 3 (BO 3 ) 4 ) установлена их принад-лежность к мультиферроикам [1,3,7].…”

“…Praseodymium and terbium iron borates crystallize into the trigonal noncentrosymmetric structure of the natural mineral huntite (space group R32), order into an easy-axis antiferromagnetic (AFM) structure [at 32 and 40 K for PrFe 3 ðBO 3 Þ 4 [21,22] [25]. Effects observed due to the 4f-electron-phonon interaction are particularly simple and clear for the interpretation in the case of PrFe 3 ðBO 3 Þ 4 that preserves the R32 (D 7…”
