Figure 2

Magnetic properties of GO measured by a superconducting quantum interference device (SQUID) magnetometer.

(a) Typical χ − T curve measured from 2 to 300 K under the applied field H = 3 kOe. Inset is the corresponding 1/χ − T curve. Red symbols are the measurements and black solid line is fitted by the Curie law. (b) M − H curve measured at 2 K. Red symbols are the measurements and black solid curve is fit to the Brillouin function with g = 2 and J = 1/2.
