A disorderedn-vector model withp spin interactions previously introduced is studied for the quenched case by means of the replica method and a generalized Parisi theory. We present formal solutions for generaln andp and then study the casep ? 8. The high-temperature solution is stable at all temperatures and there is only one phase transition at a temperatureTg. Only longitudinal lowtemperature solutions are possible. There is one spin-glass solution, and it is stable for allTg. The phase transition atTg is of first order and displays a jump discontinuity in the order parametersqj(L) andd. The spin-glass free energy is temperature dependent forn > 1 while it is constant whenn = 1. |
