Abstract The quantum spin glass theory with the infinite-range random Dzyaloshinskii-Moriya interaction presented by Yi and his cooperators is investigated numerically at a fixed anisotropy interaction for different external magnetic fields and spin number 1/2. Specifically, the dependences of the typical specific heat and entropy of spin glass on temperatures have been obtained theoretically.
