N = number of specimens for measurements, NRM = average intensity of NRM before demagnetization (standard deviation [1σ] for N ≥ 3), ARM = intensity of ARM imparted by 50.0 μT biasing field with a maximum alternating field of 180 mT (standard deviation [1σ] for N ≥ 3), Ms-T type = classified type of the thermomagnetic curves.
