Using an electric field instead of an electric current (or a magnetic field) to tailor the electronic properties of magnetic materials is promising for realizing ultralow‐energy‐consuming memory devices because of the suppression of Joule heating, especially when the devices are scaled down to the nanoscale. Here, recent results on giant magnetization and resistivity modulation in a metamagnetic intermetallic alloy, FeRh, which is achieved by electric‐field‐controlled magnetic phase transitions…
