The temperature difference in the transverse direction of the heat current is calculated for two-dimensional models with the magnetic field perpendicular to the plane. We find that there is a PHE in nanoscale paramagnetic dielectrics, the magnitude of which is comparable to millimeter scale experiments. If the dynamic matrix of the system satisfies mirror reflection symmetry, the PHE disappears. The Hall temperature difference changes sign if the magnetic field is sufficiently large or if the size increases. © IOP Publishing Ltd and Deutsche Physikalische Gesellschaft.||Source Title:||New Journal of Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/97525||ISSN:||13672630||DOI:||10.1088/1367-2630/11/11/113038|
