This work focuses on the theoretical investigation of the coexistence of superconductivity and ferromagnetism in the superconducting HoMo6S8. By developing a model Hamiltonian for the system and using the Green’s function formalism and equation of motion method, we have obtained expressions for superconducting transition temperature (Tc), magnetic order temperature (Tm), superconductivity order parameter (D) and magnetic order parameter (η). By employing the experimental and theoretical…

Coexistence of superconductivity and ferromagnetism in the d-band metal ZrZn2

The observation of superconductivity in the ferromagnetically ordered phase of the d-electron compound ZrZn2 suggests that metallic ferromagnets may universally become superconducting when the magnetization is small.

Magnetic properties of the reentrant ferromagnetic superconductor HoMo6S8

Neutron diffraction and ac susceptibility techniques have been used to study the magnetic and superconducting phase transitions in the ternary Chevrel phase system HoMo/sub 6/S/sub 8/. The material

Coexistence of ferromagnetism and singlet superconductivity via kinetic exchange.

We propose a novel mechanism for the coexistence of metallic ferromagnetism and singlet superconductivity assuming that the magnetic instability is due to kinetic exchange. Within this scenario, the

Observation of long range magnetic order in the reentrant superconductor HoMo6S8

2014 High resolution small-angle neutron scattering experiments have been carried out on HoMo6S8 to investigate the magnetic behaviour in the vicinity of the reentrant superconducting transition.

Superconductivity on the border of itinerant-electron ferromagnetism in UGe2

The observation of superconductivity on the border of ferromagnetism in a pure system, UGe 2, which is known to be qualitatively similar to the classic d-electron ferromagnets, is reported.

Ferromagnetic Superconductors

The coexistence of itinerant electron ferromagnetism and superconductivity in UGe2 and ZrZn2 raises the question if itinerant ferromagnetism is a universal precondition for certain forms of

Coexistence of superconductivity and ferromagnetism in URhGe

It is shown that the ferromagnet URhGe is superconducting at ambient pressure, and the thermodynamic signature of the transition is found—its form is consistent with asuperconducting pairing of a spin-triplet type, although further testing with cleaner samples is needed to confirm this.

Theory of Superconductivity

IN two previous notes1, Prof. Max Born and I have shown that one can obtain a theory of superconductivity by taking account of the fact that the interaction of the electrons with the ionic lattice is
