H–T Phase Diagram of the Frustrated Quantum Magnet Antlerite, Cu₃SO₄(OH)₄ — •Darren C. Peets¹, Nikolai S. Pavlovskii¹, Roman Gumeniuk², Sergey Granovsky¹, and Dmytro S. Inosov¹ — ¹IFMP, TU Dresden, Germany — ²IEP, TU Bergakademie Freiberg, Germany

The magnetic copper sites in antlerite, Cu₃SO₄(OH)₄, are arranged in three-leg triangular-lattice ladders, a unique magnetic lattice. In the ground state, the outer legs are ferromagnetic and antialigned, while the central leg is antiferromagnetic. This material has four distinct magnetic states in zero field alone, and we show that the phase diagram in applied fields is also remarkably rich.
