The authors cite R. Kubiak et al., Physica C, Vol. 166, 523 (1990), and summarize the procedure as follows. "The susceptibility was measured by a noncommercial SQUID-magnetometer in an applied field of 0.5 mT. The hydrostatic pressure was generated in a miniature Cu(Be)-pressure clamp filled with a mixture of one part of isoamyl-alcohol and one part of isopentane as a pressure transmitting medium. The pressure was determined using the superconducting transition temperature of a lead sample of 0.1 mg total weight inside the pressure cell as a manometer. The temperature was measured by a calibrated carbon-glass resistor in direct mechanical contact with one anvil of the pressure clamp."
