Abstract

Correct estimation of the heating power of magnetic nanoparticles is important for magnetic hyperthermia treatment. This letter investigates the impact of sample insulation in ac calorimetry. We show that a temperature increase in the insulation can lead to systematic errors when estimating the heating power by the corrected slope method. The errors arise if the temperature of the sample environment is kept fixed at its initial temperature in the data analysis. To correct this, the local temperature difference between the sample and the sample environment should be used.

样品绝缘对交流量热法估算磁性纳米粒子加热功率的影响

正确估计磁性纳米颗粒的加热功率对于磁热疗治疗是重要的。这封信调查了交流量热法中样品绝缘的影响。我们表明，当用修正斜率法估计加热功率时，绝缘层的温度升高会导致系统误差。如果在数据分析中样品环境的温度保持固定在其初始温度，则会出现误差。为了纠正这种情况，应使用样品和样品环境之间的局部温差。
