Stiffnessometer: When the current in a very long coil, which pierces a superconducting ring, is turned on, a persistent current is generated in the ring. The amount of current depends on the superconductor stiffness. By measuring this current via the magnetic moment of the ring the stiffness can be

Mapping exotic spin correlations in spin glasses: Keren and collaborators found experimentally that close to the spin glass transition temperature, the field-time-dependent polarization of a probing spin scales like their ratio. They interpreted this behavior using power law correlation function.

Common energy scale for magnetism and superconductivity: The Keren group demonstrated experimentally that superconductivity and magnetism in the high temperature cuprate superconductors share a common energy scale, namely, the critical temperature and the superexchange interaction strength are

Muon relaxation in a stochastic field environment: When a spin polarized muon enters a magnetic sample, it loses its polarization. The analytical relation between the muon polarization and the stochastic properties of the field is known as the Keren function.
