Abstract
In an attempt to confirm the end of the 1/3 magnetization plateau of volborthite single crystals, Faraday rotation measurements were taken in magnetic fields up to 182 T at low temperatures. Depending on whether or not the sample setting condition is free-standing, two types of 1/3 plateaus have been observed: One ends around 100 T with a plateau width about 80-90 T, and the other continues above 160 T, exhibiting an extremely wide plateau (more than 140 T). These contrasting differences are explained by the way in which the 1/3 plateau phase changes with or without a lattice distortion associated with the crystal symmetry.
