Abstract

This article focuses on the development of a metallic piston-cylinder pressure cell (PCC) made from a 56Ni–40Cr–4Al (Ni–Cr–Al) alloy designed for magnetic susceptibility measurements using a proximity detector oscillator (PDO) in pulsed magnetic fields up to 51 tesla (T) under pressures up to 2.1 gigapascals (GPa). The apparatus minimizes Joule heating effects on the sample at low temperatures (1.4 K), enabling accurate susceptibility measurements under combined extreme conditions of high pressure, high magnetic field, and low temperature. The effectiveness of this system was demonstrated by studying the pressure dependence of the magnetization process of the triangular-lattice antiferromagnet Ba3CoSb2O9, revealing pressure-induced shifts in magnetic phase transitions. This technique offers improved sensitivity over conventional induction methods by placing the sensor coil and sample inside the pressure cell, reducing noise and enhancing measurement precision in pulsed high magnetic fields.
