Temperature and biasing electric field dependences of a gyration tensor component g12 of ammoniumu sulfate were measured by using the high accuracy universal polarimeter, HAUP, together with birefringences. g12 was found to appear abruptly at the Curie point and to keep the constant value irrespective of change of the temperature. The x-rays two-dimensional method was applied for measuring the lattice strains from 300K down to 6K.
