Van der Waals materials offer the distinctive advantage that a wide range of parameters can be precisely controlled, for example through stacking with dissimilar materials and tuning by gate voltage. They have therefore become one of the ideal model systems for research in condensed matter physics. However, because their volume is extremely small, the available measurement techniques are limited, and low-energy measurements to date have largely focused on DC resistance measurements.In this talk, I will discuss studies of magnetic insulating van der Waals materials, including the quantitative evaluation of interfacial magnetoelectric effects through direct measurements of interfacial polarization, observations of magnetic dynamics in van der Waals magnets using high-frequency measurements, and measurements of superfluid stiffness and anisotropy in van der Waals superconductors.
