Abstract

We calculate the Néel temperature

T_{N}

for two-dimensional isotropic dipolar Heisenberg antiferromagnets via linear spin-wave theory and a high-temperature expansion, by employing the method of Callen. The theoretical predictions for

T_{N}

for

K_{2}

{MnF}_{4}

{Rb}_{2}

{MnF}_{4}

{Rb}_{2}

{MnCl}_{4}

, and (

{CH}_{3}

{NH}_{3}

)_{2}

{MnCl}_{4}

are in good agreement with the measured values.
