文摘
- •
We studied a magnetic transition of a natural goethite sample.
- •
15">It was observed by ESR the spin flop effect and the transition to the PM state.
- •
Spectra simulations showed ESR lines of different spins interactions with vicinity.
- •
TN was determined as 372 and 370 K by ESR and Magnetometry respectively.
