Abstract

The pressure dependence of the Néel temperature (T_N) in the antiferromagnetic Heusler alloys Ru₂MnZ (Z = Si, Ge, Sn) was investigated under hydrostatic pressure up to approximately 10 kbar. For all alloys studied, T_N decreases linearly with increasing pressure with pressure derivatives dT_N/dp of −0.64 K/kbar for Ru₂MnSi, −0.14 K/kbar for Ru₂MnGe and −0.44 K/kbar for Ru₂MnSn. Based on these findings, the magneto-volume effect in Ru₂MnZ (Z = Si, Ge, Sn) is discussed qualitatively.

静水压力对Ru2MnZ （Z = Si, Ge, Sn）纳米温度的影响

研究了反铁磁Heusler合金Ru2MnZ （Z = Si, Ge, Sn）中n温度（TN）在静水压力约为10 kbar时的压力依赖性。在所研究的所有合金中，TN随压力的增加而线性降低，压力导数dTN/dp为Ru2MnSi为- 0.64 K/kbar， Ru2MnGe为- 0.14 K/kbar， Ru2MnSn为- 0.44 K/kbar。在此基础上，定性地讨论了Ru2MnZ （Z = Si, Ge, Sn）的磁体积效应。

期刊介绍： Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged. A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions. The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
