利用邻近检测振荡器（PDO）研究了在高达51 T的磁场（$\rm\mu_0$$H $）下，压力（$P$）对CsCuCl $3 $磁化率的影响，并绘制了饱和磁场（$H_{\rmsat}$）下CsCuCl $3 $的$H$-$P$相图.我们发现，随着P$的增加，H_{\rmsat}$增加，在P$ = 0.7GPa时出现的uud相变宽。基于实验和计算的$H$-$P$相图之间的比较，Y相预测出现在1.7 GPa以上。在$ab$-平面上的链间反铁磁交换相互作用被评估并且发现随着$P$的增加而增加，这与先前在高压下的研究一致[D.山本国家通信，4263（2021）.]。此外，在P = 0.6GPa以下，H_{\rmsat}$之下观察到一个反常现象，这可能是PDO技术引起的非线性响应引起的一个新的相变.
The effect of pressure ($P$) on magnetic susceptibility of CsCuCl$_3$ was examined in magnetic fields ($\rm \mu_0$$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.
