junctions

Two-dimensional materials have gained world-wide interest in recent decade, and many phenomena that were found in bulk, such as superconductivity and magnetism, have been observed in single atomic layers. Here we experimentally study heterostructures consisting of chromium iodide, which has recently shown to display monolayer ferromagnetism, and graphene. We have fabricated high-mobility microscopic devices for low-temperature charge transport measurements. Latest data as a function of charge density, magnetic field and temperature will be discussed.
