Search for enhanced magnetism at the interface between BiSe and EuSe
K. Prokeš, Chen Luo, H. Ryll +8
Enhanced magnetism has recently been reported for the topological-insulator/ferromagnet interface BiSe/EuS with Curie temperatures claimed to be raised above room temperatu…
Signatures for spinons in the quantum spin liquid candidate CaCrO
Jonas Sonnenschein, Christian Balz, Ulrich Tutsch +6
We present new experimental low-temperature heat capacity and detailed dynamical spin-structure factor data for the quantum spin liquid candidate material CaCrO.…
The magnetic Hamiltonian and phase diagram of the quantum spin liquid Ca10Cr7O28
Christian Balz, Bella Lake, A. T. M. Nazmul Islam +6
A spin liquid is a new state of matter with topological order where the spin moments continue to fluctuate coherently down to the lowest temperatures rather than develop static lon…
Physical realization of a quantum spin liquid based on a novel frustration mechanism
Christian Balz, Bella Lake, Johannes Reuther +11
Unlike conventional magnets where the magnetic moments are partially or completely static in the ground state, in a quantum spin liquid they remain in collective motion down to the…
Luttinger-Liquid Behavior in the Alternating Spin-Chain System Copper Nitrate
B. Willenberg, H. Ryll, K. Kiefer +8
We determine the phase diagram of copper nitrate Cu(NO)2.5DO in the context of quantum phase transitions and novel states of matter. We establish this compound as…
Spin ladders and quantum simulators for Luttinger liquids
S. Ward, P. Bouillot, H. Ryll +5
Magnetic insulators have proven to be usable as quantum simulators for itinerant interacting quantum systems. In particular the compound (CHN)CuBr (short (…
Thermodynamic Properties of the Anisotropic Frustrated Spin-chain Compound Linarite PbCuSO(OH)
M. Schäpers, A. U. B. Wolter, S. -L. Drechsler +18
We present a comprehensive macroscopic thermodynamic study of the quasi-one-dimensional (1D) frustrated spin-chain system linarite. Susceptibility, magnetization…
Mutual induction of magnetic 3d and 4f order in multiferroic hexagonal ErMnO3
D. Meier, H. Ryll, K. Kiefer +4
The complex interplay between the 3d and 4f moments in hexagonal ErMnO3 is investigated by magnetization, optical second harmonic generation, and neutron-diffraction measurements.…
Solitonic lattice and Yukawa forces in the rare earth orthoferrite TbFeO3
Sergey Artyukhin, Maxim Mostovoy, Niels Paduraru Jensen +13
The control of domains in ferroic devices lies at the heart of their potential for technological applications. Multiferroic materials offer another level of complexity as domains c…
120° Helical Magnetic Order in the Distorted Triangular Antiferromagnet alpha-CaCr2O4
S. Tóth, B. Lake, S. A. J. Kimber +9
α-CaCr2O4 is a distorted triangular antiferromagnet. The magnetic Cr3+ ions which have spin-3/2 and interact with their nearest neighbors via Heisenberg direct exchange interaction…
