Quantum states are difficult to observe experimentally. In addition, ideal model materials have not been found for some of the lattice systems in which exotic quantum states are predicted to be realized. Numerous candidates for low-dimensional quantum magnets are hidden in copper minerals, and the number of candidates is increasing every year. We succeeded to synthesize seven copper minerals by imitating the environment where they are discovered and reported their quantum states. The properties of pulsed muons are very suitable for investigating the spin state of artificial copper minerals.

In recent years, many new copper minerals have been discovered in the volcanic regions of the Kamchatka peninsula. The speaker has found several frustrated low-dimensional quantum magnets in these Kamchatka copper minerals, synthesized them artificially, and investigated their spin states. In this talk, I will introduce the role of the SR method, which is a highly sensitive method for detecting spin dynamics and/or static internal magnetic fields, in these artificial minerals. The importance of complementary use with neutron scattering experiments will also be discussed.
