High field magnetic phase study on UPt2Si2

UPt2Si2 has been long considered as a rare example of uranium intermetallic compound with strongly localized f-electrons which order antiferromagnetically below TN~35K. Recent...UPt₂Si₂ 长期以来被视为一类罕见的铀基金属间化合物（uranium intermetallic compound），该化合物拥有强局域化f电子（strongly localized f-electrons），并在奈尔温度（Neel temperature, TN）约35开尔文以下发生反铁磁有序。近期……
