"currents which flow on edge of material, dissipationless, which means that the electrons don't scatter, and they don't dissipate energy... beam neutron particles... TbMn6Sn6 has competing interactions between the layers, or what is called frustrated magnetism. "So the system has to make a compromise," McQueeney said, "Usually what that means is that if you poke at it, you can get it to do different things... even though those competing interactions are there, there are other interactions that are dominant"
