Abstract:

Recent experiments on the suppression of ferromagnetism due to the spin-polarized electron liquid in half-metallic CrO2 are combined with existing band structure calculations. A semi-empirical form of the variation of Curie temperature with pressure P for P<12 GPa is thereby proposed, to be confirmed, or refined, following further high pressure experiments.
