UB$$_4$$は0.3Kまで磁気秩序を示さない、やや重いフェルミオンである。本研究では2-800Kの広い温度域でUB$$_4$$の磁性を調べた。主軸方向の磁化率のブロードなピークとして、5f電子の低温域の遍歴的振る舞いと高温域の局在的振る舞いの移り変わりが観測された。

UB$$_4$$ is a moderate heavy fermion compound which does not exhibit any magnetic order down to 0.3 K. In this work, the magnetic properties of UB$$_4$$ are investigated in an extended temperature range, 2-800 K, on high-quality single crystals. A cross-over from a low temperature 5f itinerant behaviour to a high temperature 5f localized behaviour is observed, marked by broad peaks in the magnetic susceptibility measured along the main crystallographic axes.
