Neutron diffraction shows that superconducting UPt sub 3 can be an antiferromagnet with an ordered moment of micron B and a Neel temperature (T sub N) of 5K.
We study magnetic Raman scattering in La_2-xSr_xCuO_4 (x 0.03) detwinned crystals. The anisotropic dispersion with magnetic field of the lowest spin-wave gap around 17 cm-1 is mapped in La2CuO4.
We have performed muon spin relaxation (uSR) measurements on La sub 1.85 Sr sub 0.15 CuO sub 4 above and below its superconducting transition temperature, T sub c = 37K.
Using the technique of muon-spin-rotation (mu sup + SR), we have investigated the magnetic penetration depth in single-crystal UPt sub 3 for applied fields along the c- and a- directions.

Using linear response theory, we have derived the form of a spin fluctuation-induced e-h interaction in a semi-magnetic semiconductor, in terms of spin susceptibilities.

We review experimental and theoretical aspects of bound magnetic polarons (BMP) in II-VI semimagnetic semiconductors, using the CdTe/Cd sub (1-x) Mn sub x Te system as a prototype.
We review recent theoretical and experimental work on the metal to insulator transition in doped semiconductors.
