We have used high-resolution X-ray diffraction and Raman spectroscopy to investigate structural modifications inside and outside the focal region of Si-implanted GaAs samples that have been irradiated at high power by a focused short-pulse laser. Si

We study the electronic Raman spectra of p- and n-type cuprates. In particular, we study the electronic continuum and the energy of the 2 Δ peaks that form below T c as a function of photon polarization (symmetry within the crystal). In the present

Muon spin relaxation has been measured in Sr(Cu1-xZnx)2O3. The results for low Zn concentration x 0 occurred with increasing x around x approximately 0.8%, accompanied by a change of line shape to that expected in a concentrated magnetic environment.

Muon spin relaxation (μSR) and high-field magnetization measurements have been performed in Ba8Si46, a superconductor with T c =8 K having a silicon clathrate three-dimensional cage structure. The upper critical field H c2 =6.5 T , determined from t

We have performed ZF-μSR measurements of Sr2RuO4 and have observed a spontaneous magnetic field below Tc. This observation, combined with other symmetry considerations demonstrates that superconductivity in Sr2RuO4 is of ‘p-wave’ (odd-parity) ty

We have measured muon spin relaxation (μSR) of La 8− x Sr x Cu 8 O 20 , an oxygen deficient perovskite, across two magnetic phase transitions at T = T c1 and T c2 . Static magnetic order was observed below T ∼140 K, where weak ferromagnetism app

The Heisenberg kagome antiferromagnet is a frustrated system that provides a simple model for the study of strongly fluctuating magnets with a highly degenerate ground state. Hydronium jarosite, (H3O)Fe3(OH)6(SO4)2 possesses a kagome lattice of Fe3+

We discuss the use of the Kubo Golden rule (KGR) in the derivation of new muon polarization functions for arbitrary static field distributions in both zero (ZF) and longitudinal (LF) applied fields. ZF/LF muon spin relaxation measurements in spin-lad
