Temperature dependence of magnetic anisotropy in a cylindrical Fe65Pd35 nanowire array

Magnetization of amorphous FeOOH chrysanthemum-like nanosheets under ambient conditions

“…Deriving the difference between the M ZFC and M FC magnetization curves (∂[ M ZFC − M FC ]/∂ T ) gives the profile of the blocking temperature T B distribution, which is related to the energy barrier distribution in the sample. 31 The inset of Fig. 4b shows T B appears at the clear peak of 10 K, indicating that a magnetic contribution is blocked below 10 K. The anisotropy constant at 300 K was calculated to be 2.32 × 10 4 J m −3 according to the Law of Approach to Magnetic Saturation method.…”
