Accurate quantitative method of NdFeB magnetism based on laser-induced breakdown spectroscopy NdfeB magnetic materials are widely used in daily life, such as permanent magnet motors, loudspeakers and computer disks. The NdfeB magnetic material has excellent magnetic properties, and its magnetic properties are also the key to judge the production quality of NdFeB. Therefore, the precise quantification of the magnetic properties of NdFeB magnetic materials is crucial.

AbstractAvalanche photodiodes (APDs) have enabled highly sensitive photodetection in optical communication, sensing and quantum applications. Great efforts have been focused on improving their gain–bandwidth product (GBP). However, further advance has encountered enormous barriers due to incomplete consideration of the avalanche process.
