Figure 4

Magnetic properties of the as-prepared BCN nanosheets. (a) M-H curves measured at 5 K to 350 K; the inset shows the enlargement of the hysteresis loops in the range of −500 Oe < H < 500 Oe. (b) Relationship among M s , H c , and temperature. (c) Temperature dependence of field-cooled (FC, black open circles) and zero-field-cooled (ZFC, blue open circles) magnetization at 100 Oe for the as-prepared BCN nanosheets. (d) Theoretical fitting for the FC curve by Curie-Weiss model for the low temperature region and spin-wave theory model for the high temperature region.
