Abstract

Specific heat C_p 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 C_p at T_N ∼ 6 K and T_WF ∼ 2.3 K, respectively. Under magnetic fields parallel to the [1 1 0] direction, T_N decreases monotonically with increasing field, while T_WF increases at low fields and decreases above 1 T. This re-entrant behavior of T_WF is reasonably explained by assuming the competition between magnetocrystalline anisotropy and the weak ferromagnetism arising from the magnetic moment at the AF domain boundary.
