Alloys are used in almost every product people use regularly. Scientists have recently discovered some interesting quantum effects on the alloy used in the hard disk material. The cobalt-iron alloy is the material used for most of the hard disk. Recently, researchers from Oakland University of Michigan, the Fudan University of China along with the researchers of the energy department of the United States, have discovered quantum effects on the alloy. The scientists involved in this study has discovered some totally surprising facts. Argonne material scientist- Olle Heinonen, one of the authors of the study said, the change in electron spin in the alloy material provide have many advantages.

The quantum effect in the hard disk material, cobalt-iron alloy enables the scientists to control the electron spin direction. The change in the direction of the electron spin, enable you to develop energy- efficient and more powerful material that helps in efficient information storage. More information can be stored in a smaller space by controlling the magnetic field. The quantum effects of on the alloys have many applications generators, magnetic bearings, and electric motors.

The discovery of the quantum effect is interesting as the concerned alloy is widely used and many applications in every field. The properties of the alloy have been studied properly before the research by scientists. The cobalt iron alloy material doesn’t have any desired direction for the spin of the electron. Previously, the scientists prepared cobalt iron alloy through baking the material at high temperature. It resulted in lattice arrangement of the iron and cobalt atoms. The baking method eliminates the directional effects of the atoms in the material. Now in the current research, the scientists observed the quantum effect by experimenting on the unbaked alloy.

In the current research, the atoms of iron and cobalt occupy the positions randomly unlike the past experiment in the baked method. The researchers in this study also explain the crystal structure of the alloy. Usually, in the crystal structure, the atoms of the material are arranged in symmetrical order, but in some alloys, the arrangement differs. For the perfect crystal structure, the baking method can be applied. The method will make the atoms of the alloy arrange in order. The experiment by the team calculated at the DOE office of the United States. The observations are confirmed by the computing facilities available there.

The research team explained the underlying physics of the alloy. The behaviors of the atoms are studied in different states as the atomic arrangement differs from a crystalline structure to the squeezing structure. Likewise, the atomic spin works differently in a different environment. The study shows, the working of the damping effect as it is small in some directions and vice versa. The quantum effects on the alloy have many interesting discoveries associated with it, which has many applications in different sectors. The work of the scientists is praised at every level as the discovery is highly surprising. The study can be conducted on other alloys for better efficiency.
