报道了YbAl3C3的四极有序[Tq]的最高转变温度,在该温度范围内,用比热和超声测量观察到明显的反常,磁化强度只有很小的变化,用中子衍射测量没有观察到磁性或结构相变。因此,我们认为YbAl3C3具有迄今发现的最高T_q的反铁四极有序,并首次实现了稀土金属间化合物和金属间化合物的这种超越液氮温度的有序。
We report the highest transition temperature of quadrupolar ordering [ T Q ] in YbAl 3 C 3 , where a distinct anomaly is observed by specific heat and ultrasonic measurements at 80 K. Magnetization measurements show only a very slight change and no magnetic or structural phase transitions can be observed by neutron diffraction measurements in this temperature range. Therefore, we believe that YbAl 3 C 3 shows an antiferroquadrupolar ordering with the highest T Q found to date and is the first realization of this ordering beyond liquid nitrogen temperatures for rare-earth and actinide intermetallic compounds.
