Magnetic fields affect the motion of electrons and the orientation of spins in solids, but are
thought to have little impact on crystal structure, particularly in compounds with low magnetic …

The origin of the pseudogap and its relationship with superconductivity in the cuprates
remains vague. In particular, the interplay between the pseudogap and magnetism is …

The discovery 1 of high-temperature superconductivity in copper oxides raised the
possibility that superconductivity could be achieved at room temperature. But since 1993 …

We present a study of the magnetic susceptibility χ in carefully detwinned La 2− x Sr x CuO 4
single crystals in the lightly doped region (x= 0–0.03), which demonstrates a remarkable in …

The total energy of a magnet in a magnetic field is lowest when the magnetic moment is
aligned parallel to the magnetic field. Once aligned, the magnetic moment can be reversed …

Neutron diffraction was used to determine the crystal structure and magnetic ordering
pattern of a La 2 Cu O 4 single crystal, with and without applied magnetic field. A previously …

We examine the low-temperature magnetic properties of moderately doped La 2− x Sr x
CuO 4, paying particular attention to the spin-glass phase and the commensurate …

Abstract A SPIN-½ Heisenberg antiferromagnetic ladder is a model system comprising
parallel chains of interacting elemental spins. Spin ladders having an even number of …

Since the discovery of high-T c superconductivity in La2–x Ba x CuO4–y, and related
perovskite systems1–5, the magnetic properties of the parent compound La2CuO4–y have …

Superconductivity in layered copper oxide compounds emerges when charge carriers are
added to antiferromagnetically ordered CuO2 layers. The carriers destroy the …
