| Research Abstract |
We have searched and synthesized several new geometrically frustrated magnets on the triangular, kagome and pyrochlore lattices in which interactions between spins compete with each other even on these regular lattices. We have investigated new magnetic phase transitions and magnetic states by means of several experimental methods, such as NMR, magnetization, specific heat and ESR measurements. Especially we have discovered new quantum spin liquid state, unconventional magnetic ordered states and partially ordered Kondo states.
