- Description
- Magnetic studies were conducted using lamellar tetrataenite extracted from the Toluca octahedrite by a diluted HC1 etching technique. Natural remanent magnetization (NRM) in the lamellae is very stable against AF demagnetization and is quite intense, ranging from 2.58 to 37.42 x <math>10^{-2}\,\!</math> emu/g. This NRM is completely demagnetized thermally at about 550°C. The most characteristic change in magnetic properties on heating to about 550 C° is a significant decrease in magnetic coercivity. This observation is consistent with the results obtained from chondrites. The paramagnetic component in lamellar tetrataenite, which is estimated by Mössbauer spectrum analyses, was not detected by conventional magnetic studies.
