临界指数密切匹配的N=2手征普适类已获得的层状磁性系统钴甘油使用μ子自旋弛豫。这个类最初被引入表示几何挫折三角形堆叠层XY磁体与手性非共线自旋结构。由于本磁系统是一个没有几何阻挫或手征简并的倾斜XY系统，结果表明该系统中倾斜的序参量与几何阻挫系统中的手征序参量起着类似的作用，强烈表明两种类型的非共线系统具有相同的普适类。
Critical exponents closely matching those of the N=2 chiral universality class have been obtained for the layered magnetic system cobalt glycerolate using muon spin relaxation. This class was originally introduced to represent geometrically frustrated triangular stacked-layer XY magnets with chiral noncollinear spin structures. Since the present magnetic system is a canted XY system without geometrical frustration or chiral degeneracy, the results indicate that the order parameter for canting in this system plays a similar role to the chiral order parameter in the geometrically frustrated systems, strongly suggesting that both types of noncollinear system share the same universality class.
