Magnetic microcalorimeters (MMCs) have become one of the superconducting detector technologies that demonstrate extreme energy sensitivity. MMCs utilize noble properties and advancements in superconducting sensor and electronics technology. In the presentation, the working principle of MMCs is covered in terms of the precise measurement of magnetic signals resulting from energy absorption in a detector using a superconducting circuit and a current-sensing SQUID. This presentation also highlights their best performance in the keV and MeV energy regions. Additionally, we will discuss various applications that utilize MMC as the primary detector technology.
