Transport labs
Materials with strong interactions in their interfaces and structural phase transitions are potential building blocks for functional intelligent materials. Such correlated electronic phenomenon give rise to novel underlying physics such as quantum hall effect, valley transport, topological phenomenon, unconventional magnetic ordering etc, many of which reveal themselves in electrical resistance measurements at elevated magnetic fields and ultra-low temperatures. The transport labs in I-FIM will continually be equipped with versatile cryogenic facilities that can perform such magnetotransport measurement with minimal user intervention. Each lab has been built with a separate support room to house the compressors, pumping and gas handling systems to minimize the transmitted mechanical vibration from these sources. Availability of cryostats with unique field strengths and base temperatures in I-FIM’s experimental repertoire strongly enhance our capabilities to pursue multiple projects simultaneously, with a high turnaround time. Crucially, the sample holders in the transport cryostats are compatible with the optical cryostats, to enable researchers to perform these complementary measurements in tandem and realize deliverables quickly. Going forward, plans are in place to obtain specialized apparatus for performing magnetotransport experiments in the milliKelvin range and in the presence of electromagnetic radiation spanning across the sub-THz to visible frequency domains.
