The general solutions for the factorization equations of the reflection matrices K +or- ( theta ) for the eight-vertex and six-vertex models (XYZ, XXZ and XXX chains) are found. The associated integrable magnetic Hamiltonians are derived explicitly, finding families depending on several continuous as well as discrete parameters.
