  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 to the nanoscale. In
the review, we summarize recent results on the giant magnetization and
resistivity modulation in a metamagnetic intermetallic alloy - FeRh, which is
achieved by electric-field-controlled magnetic phase transitions in
multiferroic heterostructures. Furthermore, the approach is extended to
topological antiferromagnetic spintronics, which is currently receiving
attention in the magnetic society, and the antiferromagnetic order parameter
has been able to switch back and forth by a small electric field. In the end,
we envision the possibility of manipulating exotic physical phenomena in the
emerging topological antiferromagnetic spintronics field via the electric-field
approach.
