DESCRIPTION:Speakers: Mikhail Platunov (Kirensky Institute of Physics)\nWe
  present an element-specific magnetizations study of the multiferroic Nd0.
 5Ho0.5Fe3(BO3)4 single crystal. Our experimental results confirm the coexi
 stence of three magnetic subsystems (Fe\, Ho\, and Nd). It was found that 
 the Ho magnetic moment undergoes the pronounced spin-reorientation transit
 ion. At the magnetic ield (less than 1 T) the Ho and Nd magnetization curv
 es demonstrate different of the slopes indicating different strength of f-
 d exchange interactions with iron subsystem. It was shown that the Fe magn
 etic moment behave like a weak ferromagnet\, but not antiferromagnetically
 . These magnetic findings are relevant to understand magnetism of Nd0.5Ho0
 .5Fe3(BO3)4 single crystal and other multiferroic ferroborates.\n\nThis st
