We have developed printable magnetic field sensors with full recyclability. The printing technology streamlines the fabrication process, resulting in reduced energy consumption and equipment investments. Additionally, the circularity of materials at the end of the sensors' lifespan minimizes environmental footprint. With energy-efficient fabrication and material circularity minimizing environmental impact, our sensors hold significant promise for Internet of Things (IoT) applications requiring a multitude of low-cost sensors for real-time data exchange. This potential is exemplified by the integration of magnetic sensing in smart home systems. This work is result of fruitful cooperation of the HZDR team with the group of Prof. Yuhan Wu (Shenyang University of Technology, Shenyang, China). X. Wang, L. Guo, O. Bezsmertna, Y. Wu, D.

Our paper on the discovery of the nonlinear Hall effect in elementary Bi thin films is highlighted as a cover of Nature Electronics. We demonstrate that in the elemental (semi)metal bismuth, the room-temperature nonlinear Hall effect is generated by surface states that are characterized by a Berry curvature triple: a quantity governing a skew scattering effect that generates non-linear transverse currents. The strength of nonlinear Hall effect can be controlled on demand using an extrinsic classical shape effect: the geometric nonlinear Hall effect. We performed high harmonic generation experiments to show the potential of polycrystalline Bi thin films for optoelectronic applications in the terahertz (THz) spectral domain. This work is result of fruitful cooperation of the HZDR team with the group of Prof. Carmine Ortix (University of Salerno, Italy). P. Makushko, S. Kovalev, Y. Zabila, I. Ilyakov, A. Ponomaryov, A.
