Specific heat Cp of an ErNi2B2C single crystal was measured. In the absence of a magnetic field, both antiferromagnetic (AF) and weak ferromagnetic transitions were observed as a peak and a kink in Cp at TN ∼ 6 K and TWF ∼ 2.3 K, respectively. Under magnetic fields parallel to the [1 1 0] direction, TN decreases monotonically with increasing field, while TWF increases at low fields and decreases above 1 T. This re-entrant behavior of TWF is reasonably explained by assuming the competition between magnetocrystalline anisotropy and the weak ferromagnetism arising from the magnetic moment at the AF domain boundary.
