Calculation of the electronic structure, lattice dynamics, and optical and magnetic properties of europium tetraborate EuB4O7
The electronic band structure, lattice vibration frequencies, and optical and magnetic properties of EuB 4 O 7 crystal with α-SrB 4 O 7 -type structure are calculated within the density functional method. It is found that this compound is a dielectric with a band gap of the order of 4 eV. It is foun...

-type structure are calculated within the density functional method. It is found that this compound is a dielectric with a band gap of the order of 4 eV. It is found that the ground state of this crystal is the state with ferromagnetic ordering of Eu
2+
spins. Exchange interaction constants are calculated; the ferromagnetic ordering temperature is estimated within the molecular field approximation (
T
