Comment:

The first row (heating cycle) of hysteresis data pertains to the unheated (original) sample. The second row (cooling cycle) of data corresponds to the sample heated to obtain thermomagnetic curves. For Sample 64-477A-2-2,8-10, the first two rows of data pertain to unheated samples and show the reproducibility of measurements.
