Entropic forces in classical many-body systems, eg, colloidal suspensions, can lead to the formation of new phases. Quantum fluctuations can have similar effects: spin fluctuations …
A variety of analytical techniques suggest that quantum fluctuations lead to a fundamental instability of the Fermi liquid that drives ferromagnetic transitions first order at low …
Quantum critical points (QCPs) emerge when a second-order phase transition is suppressed to zero temperature. In metals the quantum fluctuations at such a QCP can give rise to new …

The d-electron low temperature magnet NbFe 2 is poised near the threshold of magnetism at ambient pressure, and can be tuned across the associated quantum critical point by …

In this review, an overview of itinerant magnets without magnetic elements is presented, beginning with a comparison of the local and itinerant moment pictures, the two extremes of …
The Fe–Nb and Mn–Nb systems have been thermodynamically investigated within the CALPHAD approach by combining available experimental data and the data from our ab …
This paper presents a Calphad-type thermodynamic database for the Fe–Nb–Ni system. The stable phases in this ternary system are liquid, fcc_A1, bcc_A2, C14 Laves, D0a, D85 and …

We report first-principles calculations of the band structure and magnetic ordering in the C14 Laves phase compound NbFe 2. The magnetism is itinerant in the sense that the moments …
