The two-magnon (2M) excitation at 3000 cm21 in Sr14Cu24O41 two-leg ladder is studied by Raman scattering.

The spin equilibria of several derivatives of human methemoglobin were probed by resonance Raman scattering.

The spin excitations in La2CuO4, a two-dimensional spin-1/2 Heisenberg antiferromagnet and parent compound of high-T-c, superconductors, have been measured throughout the Brillouin zone using high-

We present recent studies of electronic excitations in nanofabricated AlGaAs/GaAs semiconductor quantum dots (QDs) by resonant inelastic light scattering.

We report inelastic light scattering experiments in the fractional quantum Hall regime at filling factors v less than or similar to 1/3. A spin mode is observed below the Zeeman energy.

Previous work (1) has shown that, in the presence of sp-d exchange between carriers and localized spins in a dilute magnetic semiconductor (DMS), spin fluctuations can give rise to an exchange indu

We report observation of two dimensional spin fluctuation excitations in Ba sub 2 YCu sub 3 0 sub (6-delta), with delta in the range 0.0-0.9.

Our recent reports of highly energetic spin fluctuations in cuprate insulators closely related to high-T sub c superconductors have raised the possibility that the strong spin interactions thus ma

While crystalline Tb is a helix antiferromagnet with a Neel temperature of 229K which becomes ferromagnetic at 222K, disordered Tb exhibits a spin-glass transition.

What could possibly be new in MnO 46 years after the discovery of its antiferromagnetic transition?: a spin-glass transition in the 25-50K temperature range.
