The Rocky Road to Magnetism

1. why are things magnetic ?
2. magnetic domains and magnetic grain size
   potential energy terms, resulting domains, SP, SSD, PSD, MD grains
3. Magnetic minerals
   Fe-oxides / hydroxides, Fe-sulfides, paramagnetic, diamagnetic minerals
4. Common magnetic measurements at room-temp
   4.1 magnetic susceptibility
   4.2 isothermal remanenct magnetization
   4.3 Alternating field demagnetization (AFD)
   4.4 ARM acquisition
   4.5 frequency dependence of magnetic susceptibility
   4.6 viscous effects
   4.7 hysteresis measurements
5. Common magnetic measurements at high and low-T
   5.1 Curie-temperature determinations
   5.2
