MetaMagIC deals with the efficiency of magnetic devices in information and communication technologies. Following an increasing need to achieve a precise control of magnetic fields on progressively smaller length scales – down to the nanoscale - improving the current performance of magnetic devices in terms of homogeneous magnetic field concentration in small and targeted volumes can drastically enhance the device energy efficiency. In this project, we will address these two challenges simultaneously. The project introduces a novel ground-breaking approach aiming at the conception, design, development, and implementation of magnetic metasurfaces for controlling low-frequency magnetic fields at the micro/nanoscale. With a combination of theory and modelling, and state-of-the-art techniques for fabricating and characterizing magnetic thin-film devices, we target important technological challenges: enhancing the sensitivity of magnetic sensors by the specially designed planar metamaterials; reducing the negative effects of demagnetizing fields, limiting the device performance; by using metasurfaces, exploiting the non-linear properties of the magnetic materials to achieve novel functionalities for the magnetic devices, such as self-protection of sensitive equipment to high magnetic field values; improving, with the obtained metasurfaces, the efficiency of small-scale energy harvesting materials with the goal of generating enough energy to operate low-power electronic devices.
