Description

Detailed measurements of M(2 K, H, θ) of HoNi2B2C, where θ is the angle that the applied field H makes with the [110] axis while remaining perpendicular to the crystallographic c axis, reveal three metamagnetic transitions with angular dependences Hc1=(4.1±0.1 kG)/cos(θ), Hc2=8.4±0.2 kG/cos(φ), and Hc3=(6.6±0.2 kG)/sin(φ), where φ=θ-45 is the angle from the [100] axis. The high-field saturated moment, Msat∼10μBcosθ is consistent with the local moments being confined to the [110] direction. The locally saturated moments for fields between Hci (i=1,2,3) also manifest angular dependences that are consistent with combinations of local moments along [110] axes. Analysis of these data lead us to infer that the net distribution of moments is (↑↓↑↓↑↓) for HHc3. copyright 1997 The American Physical Society
