Abstract
New results in 2H-NbSe2 system confirm the thermodynamic nature of ree ntrant characteristic of PE curve in very clean samples and show that disorder shrinks the ( H,T) region of vortex solid phase. All thermoma gnetic history effects cease at a Peak Effect boundary which we identi fy with onset of pinned vortex liquid state.
