Unformatted text preview: condition: (T-Θ )/C − |g 4 |P s 2 + g 6 P s 4 = 0 (note: the previous version incorrectly had the term g 6 P s 6 in the above equation) with T set equal T c gives one equation for the polarization P s (T c ) at the transition temperature. A further condition at the Curie point is that F(P s ,T c ) = F(0,T c ). (a) Combining these two conditions, show that P s 2 (Tc) = 3|g 4 | / 4g 6 . (b) Using this result, show that T c = Θ + 3 C g 4 2 / 16g 6 ....
