加压下MnSi中不存在磁相分离

Absence of magnetic phase separation in MnSi under pressure

D. Andreica, P. Dalmas de Reotier, A. Yaouanc, A. Amato, G. Lapertot

摘要:

我们报告μ子自旋光谱数据(muSR)在静水压力下获得的大单晶的巡回helimagnet MnSi,并记录到0.235 K和高达15.1千巴。直到临界压力p_c = 14.9(2)kbar,磁序被抑制,muSR数据明确地表明系统的基态是磁性的,没有任何相分离的迹象。

英文摘要:

We report muon spin spectroscopy data (muSR) obtained under hydrostatic pressure on a large single crystal of the itinerant helimagnet MnSi, and recorded down to 0.235 K and up to 15.1 kbar. Up to the critical pressure p_c = 14.9 (2) kbar, where the magnetic order is suppressed, the muSR data unambiguously demonstrate that the ground state of the system is magnetic with no indication of any phase separation.
