Welcome to the webpages of the Magnetoelectronics Lab (meLAB).

Since William Thomson (Lord Kelvin) discovered in 1856 that “the conducting power of an iron plate, when magnetized, became greater across than along the lines of magnetization”, magnetoresistance has become an invisible companion of our lives, notably in miniature sensors that measure linear position, angle, and rotation speed, as found in cars, as well as in electronic compasses that measure the Earth's magnetic field or the electric current in a conductor. Yet, more than 160 years later, magnetoresistance still holds hidden surprises, revealing fundamental aspects of electron conduction and enabling new technological applications.

The Magnetoelectronics lab aims to promote and support engineering and physical science research in magnetism, magnetic sensors, circuits, devices, and spintronics. Research in Magnetism is broadly ranging from theoretical, simulation, design and experimental work in fundamental physics to applications of magnetic devices, sensors, and electronics.

We are working on the sensors compatible with CMOS IC technology, allowing them to be manufactured with integrated electronic readout, produced in mass quantities (potentially at low cost), and deployed in a one-time use, disposable format for point-of-care testing. In this regard, various magnetic sensors including Hall effect sensors, Giant Magnetoresistance (GMR), Anisotropic magnetoresistance (AMR), Tunnelling magnetoresistance (TMR), spin valve sensors, SQUID sensors, magnetic resonance sensors (NMR, ESR etc.). Furthermore, we research on the magnetic tweezing to trap and manipulate the magnetic tags with a magnetic field to potentially speed up the reaction or remove unbound tags. Our study also focuses on in-depth analysis using simulation as it’s essential before an overall system to ensure the targeted functionality.
