The spin interaction effects on the Karpman-Washimi ponderomotive magnetization are investigated in quantum plasmas. The induced Karpman-Washimi magnetization and cyclotron frequency due to the ponderomotive interaction are obtained as functions of the electron quantum wave length, Fermi wave number, wave frequency, and wave number. It is found that the spin interaction correction significantly enhances the Karpman-Washimi magnetization. It is also found the Karpman-Washimi magnetization increases with increasing Fermi wave number. In addition, it is found that the spin correction effect strongly enhances the radiation spectrum. It would be expected that the Karpman-Washimi interaction can be a possible terahertz radiation mechanism in a quantum plasma.
