"TbMn6Sn6 has competing interactions between layers, or what is called frustrated magnetism... system has to compromise... even though competing interactions are there... other interactions that are dominant... This is the first detailed investigation of the magnetic properties of TbMn6Sn6 to be published. “In research... something that has not been seen before, or was understood partially or in a different manner... Electromagnets and electrical windings... to create magnetic field"
