摘要：

Magnetic sensors, based on the measurement of the magnetization of paramagnetic spins, possess characteristics that make them suitable for use with low-temperature calorimeters having large heat capacities. When the properties of the sensor. which can be calculated, are optimized for a given heat capacity, the energy resolution depends on heat capacity roughly as C-1/3. We have obtained an energy resolution of 135 eV at 6 keV with a calorimeter having a heat capacity of 4 x 10(-9) J/K. No deviations from a linear response with respect to energy were observed in the detector up to 136 keV. Prospects for the improvement of the performance of large calorimeters are discussed.
