Abstract

Applications of sensitive vibrating reed magnetometry to a variety of superconducting and magnetic materials are reviewed. The advantages of conducting vibrating reed studies of small single crystals, ceramics, thin films and multilayers with high anisotropy, composition gradients, strain and nonlinear magnetic response are documented. The equilibrium and dynamic properties of magnetic flux in superconductors, and coexistence of magnetic and superconducting states are emphasised. Vibrating reed experiments on Nb, NbSe2, (Ba0.6K0.4)BiO3, HoNi2B2C, {Nb(x)/Ni(y)}Z multilayer films, and κ-(ET)2Cu{N(CN)2}Br have revealed subtle, exotic superconducting behaviours that remain unexplained. Future prospects for vibrating reed measurements of ferromagnetic thin films with patterned nanostructures are considered.
