  We present the formalism of linear response theory both at zero and finite
temperature in the case of asymmetric nuclear matter excited by an isospin flip
probe. The particle-hole interaction is derived from a general Skyrme
functional that includes spin-orbit and tensor terms. Response functions are
obtained by solving a closed algebraic system of equations. Spin strength
functions are analyzed for typical values of density, momentum transfer,
asymmetry and temperature.
