1. A multi-layered material for shielding low-frequency electromagnetic waves, the multi-layered material comprising:
a plurality of repeating sets of alternating layers of material, each repeating set of alternating layers comprising:
an electrically conductive layer consisting of a two-dimensional transitional metal carbide (MXene) layer; and
a magnetic layer comprising a continuous layer of a magnetic material in direct and continuous contact with the electrically conductive layer,
wherein the multi-layered material is configured to shield electromagnetic waves having a frequency of less than about 1 MHz.
