The European research institution Jülich just released new information on “zero-point energy” and its effect on the stability of nanomagnets. If scientists can determine how to magnetically store data, information can be stored in extremely small spaces.
Quantum mechanics becomes important when we’re talking about small spaces, such as nanometers. Magnetic moments are difficult to stabilize, or point in designated directions. A specific direction corresponds to effectively storing data.
In order to save data, the magnetic moments of atoms in constant motion must be counteracted by energy barriers, which is dependent on the material used. Otherwise, the magnetic moments change and any information saved is then lost.
