抄録	A uranium-based metallic compound UNi4⁢B with an orthorhombic structure exhibits antiferromagnetic (AFM) ordering at 𝑇N=20.4 K. Although an electric current-induced magnetization below 𝑇N has been observed in this compound [H. Saito et al., J. Phys. Soc. Jpn. 87, 033702 (2018)], its underlying mechanism remains controversial. In this study, we measured thermal expansion and magnetostriction along the 𝑎 axis under a magnetic field 𝐻 up to 14 T applied within the 𝑏𝑐⁢ plane to investigate the rotational symmetry of a magnetic field–temperature (𝐻−𝑇) phase diagram in UNi4⁢B. From the phase diagrams constructed under various 𝐻 angles between 𝑏 and 𝑐, it is suggested that the 𝐻−𝑇 phase diagram practically exhibits sixfold rotational symmetry within the 𝑏⁢𝑐 plane despite an orthorhombic crystal structure, which would be attributed to a quasihexagonal structure formed by U ions with small orthorhombic distortion.
