A team of researchers from the University of Tokyo has developed a new type of single crystal that exhibits promising electric field control of magnetism. The crystals, made of a manganese-bismuth oxide compound, could lead to new types of electronic devices that use electric fields to control magnetic properties.

Electric Field Control of Magnetism

The ability to control magnetism with electric fields is a highly desirable property for a number of applications, such as magnetic recording, spintronics, and magnetic sensors. However, most materials that exhibit this property are either difficult to grow or require high electric fields.

The new single crystals developed by the University of Tokyo team overcome these challenges. They are relatively easy to grow and require only a small electric field to switch their magnetic properties.

Promising Applications

The new single crystals could have a number of promising applications, including:

* Magnetic recording: The crystals could be used to create new types of magnetic recording devices that are smaller, faster, and more energy-efficient than current devices.

* Spintronics: The crystals could be used to create new types of spintronic devices, which use the spin of electrons to store and process information.

* Magnetic sensors: The crystals could be used to create new types of magnetic sensors that are more sensitive and accurate than current sensors.

Further Research

The University of Tokyo team is currently conducting further research on the new single crystals. They are investigating the material's properties in more detail and exploring potential applications for the material.

The development of the new single crystals is a significant step forward in the field of electric field control of magnetism. The crystals have the potential to enable new types of electronic devices that are smaller, faster, and more energy-efficient than current devices.
