概要
- 論文の詳細を見る
We present a detailed study of the high pressure phase diagram of the non-centrosymmetric antiferromagnet CeCoGe3 by measurements of the ac calorimetry in a diamond anvil pressure cell. Under high pressure the magnetic ordering temperature shows a step like decrease due to various successive magnetic phases under high pressure. The magnetic order disappears at a critical pressure of $ p_{\text{c}}\approx 5.5$ GPa. Around the critical pressure bulk superconductivity has been detected in the ac calorimetric measurement.
