Abstract
The magnetization curves as a response of sweeping magnetic field in the thermal environment are investigated using the quantum master equation. In a slow velocity region where the system almost behaves adiabatically, the magnetic plateau appears which has been observed in the recent experiment of V [ Phys. Rev. Lett. (2000)]. We investigate its mechanism and propose that this phenomenon is quite universal in the quasi-adiabatic transition with small inflow of the heat, and we call it 'Magnetic Foehn Effect'. We observe the crossover between this mechanism and the Landau-Zener-St\"{u}ckelberg mechanism changing the velocity. Some experiment is proposed to clarify the inherent mechanism of this effect.
