Pressure-induced weak ferromagnetism and suppression of valence transition in Yb compound

研究成果: Contribution to journalReview article査読

抄録

We have paid attention to the ground state of the high-temperature magnetic phase of YbInCu4 which exhibits a first-order valence transition at 42 K. The high-temperature phase, which shows Curie-Weiss paramagnetism of Yb3+, is stabilized down to zero temperature by the application of pressure and/or substitution of Y for Yb. We have measured magnetization of Yb0.8Y0.2InCu4 under high pressure in the low temperature ranges down to 0.6 K and could observe suppression of the valence transition and occurrence of ferromagnetism at the same time. The ferromagnetism is characterized by a low Curie temperature of 1.8 K and very small spontaneous magnetization of 0.067 μB/Yb.
