热剩余磁性，简称热剩磁，英文为Thermoremanent magnetization（TRM）。在恒定磁场作用下，岩石从居里点以上的温度，逐渐冷却到居里点以下，从通过居里温度开始，受磁化所获得的剩磁，称热剩余磁性。
热剩磁针在1040年前就已经被制造出来，为海员们所用。 到1119年这种技术已经很常见。
Thermo-remanence needles were being produced for mariners by the year 1040, with common use recorded by 1119.
通过等温剩磁和三轴热退磁实验确定了样品中的主要载磁矿物为赤铁矿。
We find that hematite is the main magnetic carrier mineral according to isothermal remanent magnetization acquisition and demagnetization of three orthogonal isothermal remanent magnetization.
热退磁处理可有效分离次生粘滞剩磁(低温分量)和原生剩磁(高温分量)。
Secondary viscous remanence (low-temperature component) and primary remanence (high-temperature component) can be effectively separated by thermal-demagnetizing process.
