Low-temperature specific-heat studies on two square-kagome antiferromagnets

Bo Liu, Zhenyuan Zeng, Aini Xu +5

We studied the low-temperature specific heats of two antiferromagnets with the two-dimensional square-kagome structure, i.e., KCu${}_6$AlBiO${}_4$(SO${}_4$)${}_5$Cl (KCu6) and Na${}_6$Cu${}_7$…
