Impact of strong disorder on the static magnetic properties of the spin-chain compound BaCu_{2}SiGeO_{7}

Joël Mesot, Krunoslav Prsa

The disordered quasi-one-dimensional magnet BaCu2SiGeO7 is considered as one of the best physical realizations of the random Heisenberg chain model, which features an irregular distribution of the exchange parameters and whose ground state is predicted to ...

Origin of Interface Magnetism in BiMnO_{3}/SrTiO_{3} and LaAlO_{3}/SrTiO_{3} Heterostructures

Harald Brune, Stefano Rusponi, Violetta Sessi

Possible ferromagnetism induced in otherwise nonmagnetic materials has been motivating intense research in complex oxide heterostructures. Here we show that a confined magnetism is realized at the interface between SrTiO3 and two insulating polar oxides, B ...

Magnetization and specific heat of the dimer system CuTe2O5

Helmuth Berger, Zheng Wang

We report on magnetization and specific heat measurements on single-crystalline CuTe2O5. The experimental data are directly compared to theoretical results for two different spin structures, namely an alternating spin-chain and a two-dimensional (2D) coupl ...

Unconventional magnetization plateaus in a Shastry-Sutherland spin tube

Frédéric Mila, Salvatore Manmana, Jean-David Picon

Using density matrix renormalization group (DMRG) and perturbative continuous unitary transformations (PCUTs), we study the magnetization process in a magnetic field for all coupling strengths of a quasi-1D version of the 2D Shastry-Sutherland lattice, a f ...

Crystal Structure and Magnetic Properties of Two New Antiferromagnetic Spin Dimer Compounds; FeTe3O7X (X = Cl, Br)

Jia Liu, Helmuth Berger, Dong Zhang

Two new isostructural layered oxohalides FeTe3O7X (X = Cl, Br) were synthesized by chemical vapor transport reactions, and their crystal structures and magnetic properties were characterized by single-crystal X-ray diffraction, Raman spectroscopy, magnetic ...

Magnetic properties of the magnetoelectric compound Cu2OSeO3: Magnetization and Se-77 NMR study

Jean-Philippe Ansermet, Helmuth Berger, Simon Granville

We present magnetization and Se-77 Nuclear Magnetic Resonance (NMR) measurements in single crystals of the magnetoelectric compound Cu2OSeO3. The temperature and field dependence of the magnetization suggest a ferrimagnetic ordering at T-c similar or equal ...

Distribution of NMR Relaxations in a Random Heisenberg Chain

Joël Mesot, Krunoslav Prsa

NMR measurements of the Si-29 spin-lattice relaxation time T-1 were used to probe the spin-1/2 random Heisenberg chain compound BaCu2(Si1-xGex)(2)O-7. Remarkable differences between the pure (x = 0) and the fully random (x = 0.5) cases are observed, indica ...

Slotless Permanent-Magnet Machines: General Analytical Magnetic Field Calculation

Yves Perriard, Pierre-Daniel Pfister

This paper presents a general analytical model for predicting the magnetic field of slotless permanent-magnet machines. The model takes into account the effect of eddy currents in conductive regions and notably in conductive permanent magnets without negle ...
