A Compact Maintenance-Free 35 Tesla Pulse Magnetic Field Setup Powered by Mains Electricity

Abstract

This article reports on the pulsed magnetic field setup designed and built to measure galvanomagnetic properties of materials in the temperature range of 2.2–310 K. The measurement system employs a six-probe method with one current and two voltage pairs. A pulse magnetic field of up to 35 T, with a recorded pulse duration of about 12 ms, is generated by discharging the capacitors’ bank through the multiturn copper solenoid. Voltage between probes is recorded using three separate measurement channels in an analog-to-digital converter featuring ∼1 µs conversion time. In one magnetic field pulse, the magnetoresistance and Hall curves are measured at specific temperature and polarities of the magnetic field and current. Measurement data processing and post-processing are implemented using programs that were written specifically for this setup, which led to the high automation level of the measuring process. Maintenance-free operation, compact size, low consumption of cryogenic liquid, and usage of only mains electricity are the main advantages of the setup. The feasibility and applicability of the setup have been proven by 14 published peer-reviewed articles.
