Figure 4

Magnetization (a) and inverse magnetic susceptibility (b) of pristine and electrochemically cycled Mn3O4@CNT, measured at B = 0.1 T (FC); note the different ordinate scales in (b). The solid (dashed) vertical line indicates the ferrimagnetic (antiferromagnetic) ordering temperature in Mn3O4 (MnO). Inset (b): Field-cooled/zero-field-cooled magnetization of Mn3O4@CNT obtained at B = 0.01 T.
