Canadian company invented magnetoresistance graphene
Saint Jean Carbon Inc. Canadian company carbon science engaged in the exploration of natural graphite properties and related carbon products, is pleased to announce the Company with the University of Western Ontario has created the first graphene that has magnetic field referred to as Magnetoresistance (MR). Creating this effect at an atomic scale is a tremendous step forward in the overall research and development of the Company`s future in graphene products.
Jin Zhang Ph.D., Associate Professor, Department of Chemical and Biochemical Engineering at the University of Western Ontario, commented: “Magnetoresistance (MR) refers to the significant change of electrical resistance of materials under a magnetic field. Magnetoresistance effects have been applied in magnetic sensors, spintronic devices, and data storage. Magnetic sensors are extremely useful for today`s industry for measurement and control purposes. The noncontact switching with magnetic sensors allows airplanes to fly with higher safety standards.
Sensitive magnetic sensors allow automobiles to determine positions in several places such as the engine crankshaft and wheel braking. The miniaturized magnetic sensors used in magnetic data storage allow computers to have significant memory. Magnetic sensors can turn home appliances such as refrigerators and washing machines into smart devices. This happens by detecting changes in electrical resistance brought on by the presence of a magnetic field. This is also known as magnetoresistance (MR). The market size of the magnetic sensor is increasing with the annual growth rate at 10% because of new nanomaterials. As part of the University of Western Ontario, we have been developing magnetic sensors by using graphene-based products with MR effects.”
Magnetoresistance (MR) of 8 is observed in our developed hybrid nanosheets. A time-efficient process was developed to deposit magnetic crystals on graphene sheets. The microstructures of the hybrid nanosheets were investigated by transmission electron microscope as shown in Figure below;
Paul Ogilvie, CEO, commented: “As the Company continues to move deeper into graphene production, the closer we get to the materials that have real life applications. As in energy creation and energy storage that will help the performance of the electric cars in the future, through greater efficiency, more conductivity and lighter, smaller parts.”
Saint Jean Carbon is a publicly traded junior mining exploration company with graphite mining claims on five 100% Company-owned properties located in the province of Quebec in Canada. The five properties include the Walker property, a past producing mine, the Wallingford property, the St. Jovite property, East Miller and Clot Property. The Company also holds the Page graphite property in Ontario.
