Single-unit-cell thick Mn3O4 nanosheets

Single-unit-cell thick Mn3O4 sheets were synthesized in an aqueous solution at room temperature. These nanosheets have a < 001 > orientation and are terminated at the Mn2O4 atomic layer. Due to the huge shape anisotropy, they demonstrated lower T-C and much greater coercivity than those of bulk Mn3O4, respectively.
