We present five magnetic impulse events observed at South Pole and in the magnetically conjugate area at Iqaluit.

We solve the problem of a magnetic impurity in a d sub x sup 2 - sub y sup 2 -wave superconductor by a variational method.

Since the introduction of the dial-type telephone switching systems, switching devices such as relays and electromagnets have become the most essential and widely used of all the components in the

Latching relays or lock-up relays, as tliey are sometimes called, are becoming important and very useful as switching elements.

HE modern alternating current bridge, with its high precision and sensitive balance, has almost completely superseded the ballistic galvanometer for determining the magnetic properties of core mate

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.
