英文摘要Noncentrosymmetric PrAlGe is considered to be a magnetic Weyl semimetal that breaks both time-reversal and inversion symmetry, in which the Weyl nodes can be moved by magnetization. However, the magnetic interaction of this system remains poorly understood. In this work we perform a systematical investigation on magnetic properties and critical behaviors in single-crystal PrAlGe. The temperature, field, and angle dependence of magnetization reveal a strong magnetic anisotropy along the c axis and absolute isotropic characteristic in the ab plane. By fitting to the magnetic entropy change [Delta S-M(T, H)] around the critical temperature T-C = 16 K, critical exponents beta = 0.136(6), gamma = 1.801(7), and delta = 14.2(6) are obtained. Based on the obtained critical exponents, Delta S-M(T, H) and M(T, H) curves are scaled into universality curves under the framework of universality principle. The critical behaviors and exponents suggest that the magnetic interaction in PrAlGe is of a two-dimensional Ising type, revealing a uniaxial magnetic interaction along the c axis. However, the ordering moments are tilted from the c axis, which causes antiferromagnetism in the ab plane. The clarification of the magnetic interaction and magnetic structure is of significance for unveiling its interplay with topological properties in this system.
