Therefore, Sr₄Ru₃O₁₀, a T_C = 105 K ferromagnet, has attracted much attention in recent years, because it develops a pronounced metamagnetic anomaly below T_C for magnetic fields applied in the crystallographic ab-plane. The metamagnetic transition moves to higher fields for lower temperatures and splits into a double anomaly at critical fields H_{c1} = 2.3 T and H_{c2} = 2.8 T, respectively. Here, we report a detailed study of the different components of the magnetization vector as a function of temperature, applied magnetic field, and varying angle in Sr₄Ru₃O₁₀. We discover for the first time a reduction of the magnetic moment in the plane of rotation at the metamagnetic transition. The anomaly shifts to higher fields by rotating the field from H ⟂ c to H ∥ c. We compare our experimental findings with numerical simulations based on spin reorientation models taking into account magnetocrystalline anisotropy, Zeeman effect and antisymmetric exchange interactions. While Magnetocrystalline anisotropy combined with a Zeeman term are sufficient to explain a metamagnetic transition in Sr₄Ru₃O₁₀, a Dzyaloshinskii-Moriya term is crucial to account for the reduction of the magnetic moment as observed in the experiments.enCC BY 4.0 (Attribution)©2017 The Authorshttp://creativecommons.org/licenses/by/4.0/FerromagnetismCrystalsAnisotropyMagnetic crystalsarticleWeickert, Franziska, Leonardo Civale, Boris Maiorov, Marcelo Jaime, et al. 2017.
