摘要: Abstract The anomaly in the temperature dependence of magnetic linear dichroism a weak ferromagnet FeBO 3 has been revealed at T N . It is explained by condensation local ,ode associated with absorption light quantum pair neighboring ions from different sublattices antiferromagnet. shown that same phenomenon leads to appearance additional lines optical spectra antiferromagnets.
