Abstract

The electrical resistivity and magnetoresistance of a 5f band metamagnet UCoAl have been measured under high pressure. It is found that the ferromagnetic spin fluctuations and the metamagnetism of UCoAl are suppressed with increasing pressure. As a consequence, the increase of 5f ligand hybridization makes the electrical resistivity behavior to be Fermi liquid-like one. A positive magnetoresistance anomaly has been detected at higher pressures just before vanishing the first-order metamagnetic transition. It may be connected with another critical phenomena of UCoAl under multi-extreme conditions.
