QUANTUM HEISENBERG S=1 2 SPIN-GLASS WITH FERROMAGNETIC COUPLING AND RANDOM DZYALOSHINSKII-MORIYA INTERACTIONS/

By means of the generalized static replica symmetric spin glass theory , a quantum Heisenberg S=1/2 spin glass model with the infinite-ranged random Dzyaloshinskii-Moriya (DM) interaction and ferromagnetic coupl ing is investigated. The dependence of entropy, specific heat, suscept ibility and the corresponding order parameters on temperature is studi ed numerically for different ferromagnetic interactions and fixed anis otropy. Two spin glass phases has been found including transverse and mixed spin glass phases. It has been shown that the local susceptibili ty exhibits double-cusp features for different ferromagnetic coupling (J(0)). Phase transition poins are found in the specific heat-temperat ure plane at various ferromagnetic coupling values. Additionally, the dependence of the spontaneous moment on temperature is calculated.
