论文摘要
使用接近检测器振荡器（PDO）和$ h $ - $ h $ - $ h $ - $ p $相位图（$ _3 $ _3 $ ymm sat a $ s sat a $ s s ymms sats SAT），压力（$ p $）对磁场（$ \rmμ_0$$ h $）在磁场（$ \rmμ_0$$ H $）中的磁敏感性的影响最高为51 t。我们发现，随着$ p $的增加，$ h _ {\ rm sat} $增加，而uud-phase出现在$ p $ = 0.7 gpa加宽。根据实验和计算的$ h $ - $ p $相图之间的比较，预计Y期将显示在1.7 GPA以上。评估了$ AB $平面中的链链抗磁磁交换交互作用，并发现随着$ p $的增加而增加，这与先前在高压下的研究一致[D. D. Yamamoto {\ it等人}，nat。社区。 {\ bf 12}，4263（2021）。]。此外，在$ p $ = 0.6 GPA以下观察到异常，略低于$ h _ {\ rm sat} $，可能是由PDO技术引起的非线性响应得出的新相变。
The effect of pressure ($P$) on magnetic susceptibility of CsCuCl$_3$ was examined in magnetic fields ($\rm μ_0$$H$) of up to 51 T using a proximity detector oscillator (PDO), and the $H$-$P$ phase diagram of CsCuCl$_3$ was constructed over the saturation field ($H_{\rm sat}$). We found that, with increasing $P$, $H_{\rm sat}$ increases and the uud-phase that appeared at $P$ = 0.7 GPa widened. Based on comparison between the experimental and calculated $H$-$P$ phase diagrams, the Y-phase was predicted to appear above 1.7 GPa. The interchain antiferromagnetic exchange interaction in the $ab$-plane was evaluated and found to increase with increasing $P$, which is consistent with a previous study under high pressure [D. Yamamoto {\it et al.}, Nat. Commun. {\bf 12}, 4263 (2021).]. Moreover, an anomaly was observed below $P$ = 0.6 GPa just below $H_{\rm sat}$ and might be a new phase transition derived from nonlinear response caused by the PDO technique.
