In this study, we examine variation of the thermal expansion ?p with the isothermal compressibility KT at various temperatures (1 atm) close to the ?-ß transition in quartz using the experimental data from the literature. ...

Chromium (Cr) undergoes a first order Neel transition as an antiferromagnetic material. When V, Mo and Mn atoms are substituted in the Cr lattice, a weak first order Neel transition in pure Cr changes toward a second order ...
