They may allow for superconductivity at higher temperatures than traditional superconductors that are mediated by lattice vibrations. We used CeCoIn5 as a laboratory to study how magnetic fluctuations can pair electrons and give rise to superconductivity. Our small-angle neutron experiments revealed how high magnetic fields break up electron pairs in the vortex cores, leading to a novel type of vortex structure that is composed of both superconducting ring currents and magnetized states.
The first superconductor was discovered nearly a hundred densation in cold atomic gases or quantum fluids such as He4. The superconductivity at relatively high temperatures.

The present electronic state of a superconducting phase consists of a understanding of conventional, phonon mediated supercon- single macroscopic quantum state, and so there is no resist- ductors suggests that they cannot yield superconductivity at ance to transport electrons. This is similar to the Bose con- sufficiently high temperatures.
However, magnetic fluctuations with energies much higher than those of phonons could instead provide the glue for Cooper pairs, possibly leading to superconductivity at higher temperatures. It features strong antiferromagnetic spin fluctuations that are believed to mediate superconductivity . The energy of the magnetic fluctua- c tions is relatively low, so the materials properties can be substantially tuned by magnetic fields and pressure.
This means the study of the interplay between superconductivity and magnetism can be carried out in a controlled fashion. This stunning observation represents a complete depar- from the superconducting to the insulating phase.

These are called vortices and form a regular two- it is important that CeCoIn5 be a Pauli-limited superconductor. With increasing magnetic fields, magnetic fields directly break up Cooper pairs and not because the vortices move closer together until superconductivity is of super-currents .
As a result, the breaking of the Cooper destroyed.

Their theory is surprisingly simple and is based on has localized magnetic moments . The combination of super- only two parameters: the coherence length of the supercon- currents and magnetized states in CeCoIn5 leads to a com- ducting condensate and the field penetration depth.
Our results constitute the first experimental evidence for a novel vortex structure in a superconductor without localized magnetic moments and demonstrate that the AG model of superconducting vortices has to be extended to include the coupling of the magnetic field to the Cooper pair.
