Description
In this talk, I will focus on is the levitated ferromagnetic spin sensor, which offers significant advantages due to its weak coupling with the environment, enabling superior noise isolation[1][2]. Additionally, the strong spin correlation within the ferromagnetic sensor provides promising noise suppression and signal enhancement capabilities, particularly in experiments probing the low-frequency regime. These features make levitated ferromagnetic spin sensors highly sensitive and well-suited for both new physics searches and real-world applications.
