Abstract: | A study of crystallographic and uniaxial anisotropy in monocrystalline Li-ferrite films in the temperature range 4.2–550°K is presented. The experimental results K1(T) agree well with calculations based on the one ion model with crystalline field coefficients of aA=–2.77 ·10–2 cm–1, aB=3.34 · 10–2 cm–1. An experimental function Ku(T) is obtained which does not contradict the assumption that anisotropic stresses are responsible for the development of uniaxial anisotropy in Li-ferrite films.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 8, pp. 113–116, August, 1973. |
