The discovery of magnetism by the ancient Greeks was enabled by the natural occurrence of
lodestone–a magnetized version of the mineral magnetite. Nowadays, natural minerals …

When quantum fluctuations destroy underlying long-range ordered states, novel quantum
states emerge. Spin-liquid (SL) states of frustrated quantum antiferromagnets, in which …

We have synthesized high-quality single crystals of volborthite, a seemingly distorted
kagome antiferromagnet, and carried out high-field magnetization measurements up to 74 T …

We report results of magnetic susceptibility and 51V-and 63, 65Cu-NMR measurements on
a high-quality powder sample of vesignieite BaCu3V2O8 (OH) 2, a candidate for the spin …

We report on the microscopic magnetic modeling of the spin-1 2 copper mineral malachite at
ambient and elevated pressures. Despite the layered crystal structure of this mineral, the …

In this letter, we identify a noncoplanar chiral spin texture on the distorted kagomé-lattice
antiferromagnets induced by the presence of a magnetic field applied perpendicular to the …

Volborthite Cu3V2O7 (OH) 2· 2H2O is a copper mineral that materializes a two-dimensional
quantum magnet comprising a kagome net of spin-1/2 Cu2+ ions. We prepared single …

Searching for the ground state of a kagomé Heisenberg antiferromagnet (KHA) has been
one of the central issues of condensed-matter physics, because the KHA is expected to host …

New and exotic ground states of magnetic materials are highly sought after and are
extensively studied for the insights they provide into the thermodynamics of disorder and …
