Abstract

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