Platinum-Precious Metal ,an excellent conductor, No Magnetic properties.
We can tune Magnets electrically by changing the number of carriers inside, which is one of the key ideas in spintronics.
Device was built in which ferro Magnetism is induced in Non-Magnetic platinum using a field effect generated by gating through an ionic medium called ionic liquid.
If an electric field is applied, the ions move to the surface of the platinum, carrying both charge and magnetic moment.
Both affect the surface layer of the platinum film, creating an atomically thin layer of magnetic platinum.
We were able to show that this is really a 2D magnet, and the magnetic state can extend to the room temperature.
Many 2D magnets have been isolated from layered compounds, but most are insulators and they are only magnetic at very low temperature.
Making them in a conductor could be useful in spintronics, a promising new type of electronics, which is based on the magnetic moment (or spin) of electrons.
The new discovery means that magnetism can be switched on and off in a conductor, which could lead to the development of devices that can simultaneously control charge and spin.
