Abstract

Electron paramagnetic resonance of

{Fe}^{3 +}

in the strong trigonal field of a nearest-neighbor substitutional arsenic in ZnSe is reported. Superhyperfine structure is observed from the four nearest neighbors - one arsenic and three seleniums. The parameters appearing in an effective spin Hamiltonian with

S = \frac{1}{2}

are

g_{∥}^{e} = 2. 0238

g_{⊥}^{e} = 6. 168

A ({Fe}^{57}) = 6. 2 \times 10^{- 4}

{cm}^{- 1}

B ({Fe}^{57}) = 16. 8 \times 10^{- 4}

{cm}^{- 1}

K_{∥} ({As}^{75}) = 8. 71 \times 10^{- 4}

{cm}^{- 1}

, and

K_{⊥} ({As}^{75}) = 16. 20 \times 10^{- 4}

{cm}^{- 1}
