Synopsis: Mining: Minerals: Garnet:

The magnetic insulator Shi and his team used was yttrium iron garnet grown by laser molecular beam epitaxy in his lab. The researchers placed a single-layer graphene sheet on an atomically smooth layer of yttrium iron garnet.

They found that yttrium iron garnet magnetized the graphene sheet. In other words graphene simply borrows the magnetic properties from yttrium iron garnet.

Magnetic substances like iron tend to interfere with graphene's electrical conduction. The researchers avoided those substances

and chose yttrium iron garnet because they knew it worked as an electric insulator which meant that it would not disrupt graphene's electrical transport properties.

but simply placing it on the layer of yttrium iron garnet they ensured that graphene's excellent electrical transport properties remained unchanged.

They found that graphene's Hall voltage-a voltage in the perpendicular direction to the current flow-depended linearly on the magnetization of yttrium iron garnet (a phenomenon known as the anomalous Hall effect seen in magnetic materials like iron and cobalt.

electrons have had to be held in place in a ferromagnetic insulator material, like yttrium iron garnet (YIG.

It was during this experimentation with different materials that Wu found himself working with YIG on a substrate of paramagnetic gadolinium gallium garnet (GGG.

such as yttrium iron garnet (YIG. When they apply a heat gradient across the material, the spins begin to"move"--that is,

Wu looked at a layer of ferromagnetic YIG on a substrate of paramagnetic gadolinium gallium garnet (GGG.

This method uses magnetic fields to break the time-reversal symmetry with certain specialized garnet and ferrite materials.

scientists have kept typically electrons stationary in a lattice made of an insulating ferromagnetic material, such as yttrium iron garnet (YIG).
