Although a spin - liquid state has previously been observed
in herbertsmithite, there has never been a detailed analysis of how the
material's
electrons respond to light — a key to determining which of several competing theories about the
material is correct.
Now an international team led by scientists at the Pacific Northwest National Laboratory has shown that how
electrons respond to radiation
in a solid can alter the way permanent damage is created
in the
material and radically affect its mechanical, magnetic, electrical, and optical properties.
