Constant of Verde of aluminium-rare-earth garnets

Abstract

The model of local optical dipoles [1] for an explanation of the nature of dependence of a constant of Verde of aluminium-rare-earth granates from the magnetic moment of an ion of rare-earth element m_BgJ (m_B-magneton of Bohr, g and J – the factor of Lande and the angular moment of a 4f-shells, accordingly) is considered. Research has shown that Faraday rotation in the aluminium-rare-earth garnets R₃Al₅O₁₂ (R=Tb, Dy, Ho, Er, Tm, Yb) [4] is caused, as well as electric polarizability RIG[3], the local magnetic fields created by 4f-shellss of rare-earth elements (type interaction «spin-another’s an orbit») and operating, in essence, within nuclear radius of rare-earth elements.
