Local magnetic and structural properties of the low-temperature orthorhombic to low-temperature tetragonal transition: A
La nuclear quadrupole resistance ~NQR! and relaxation measurements in lightly hole-doped La1.82xEu0.2SrxCuO4 have been used to investigate the microscopic properties of the low-temperature orthorhombic to low-temperature tetragonal transition. The transition is characterized by a sharp peak in La NQR relaxation rate, indicating phonon softening. We find that the structural phase transition is a...
متن کاملStripe-tetragonal first-order phase transition in ultrathin magnetic films
We analyze the nature of the phase transition from a smectic stripe phase to a tetragonal phase predicted in analytic studies by Abanov et al. @Phys. Rev. B 51, 1023 ~1995!# and observed in experiments on ultrathin magnetic films by Vaterlaus et al. @Phys. Rev. Lett. 84, 2247 ~2000!#. At variance with existent numerical evidence, we show results of Monte Carlo simulations on a two-dimensional m...

متن کاملTetragonal phase of epitaxial room-temperature antiferromagnet CuMnAs.
Recent studies have demonstrated the potential of antiferromagnets as the active component in spintronic devices. This is in contrast to their current passive role as pinning layers in hard disk read heads and magnetic memories. Here we report the epitaxial growth of a new high-temperature antiferromagnetic material, tetragonal CuMnAs, which exhibits excellent crystal quality, chemical order an...
متن کاملPressure-driven Quantum Phase Transition
The zero-temperature quantum phase transition (QPT) is driven by quantum fluctuations, in contrast to the more familiar finite temperature transitions driven by thermal fluctuations. This paper demonstrates our work on two kinds of QPTs in two different materials, respectively. The first work focuses on the pressure-driven antiferromagnetic QPT in pure chromium which is a model system for study...
