Superconductivity and Quantum Phase Transitions in Weak Itinerant Ferromagnets
It is argued that the phase transition in low-Tc clean itinerant ferromagnets is generically of first order, due to correlation effects that lead to a nonanalytic term in the free energy. A tricritical point separates the line of first order transitions from Heisenberg critical behavior at higher temperatures. Sufficiently strong quenched disorder suppresses the first order transition via the a...
متن کاملSpin and Orbital Order in Itinerant Ferromagnets
The long-standing problem of the effect of correlations on the ferromagnetism of transition metals is apparently nearing solution. The ferromagnetism of transition metal compounds, for instance doped manganites, poses a new question: is there some kind of orbital order coexisting with itinerant ferromagnetism? The ideas and techniques introduced by Gutzwiller should be of use again.
متن کاملDynamics of Weak First Order Phase Transitions.
The dynamics of weak vs. strong first order phase transitions is investigated numerically for 2+1 dimensional scalar field models. It is argued that the change from a weak to a strong transition is itself a (second order) phase transition, with the order parameter being the equilibrium fractional population difference between the two phases at the critical temperature, and the control parameter...
متن کاملSpin-Waves in itinerant ferromagnets
We introduce a novel approach for the investigation of spin-wave excitations in itinerant ferromagnets. Our theory is based on a variational treatment of general multi-band Hubbard models which describe elements and compounds of transition metals. The magnon dispersion is derived approximately as the energy of a variational spin-wave state in the limit of large spatial dimensions. A numerical e...
متن کاملWeak First Order Phase Transitions in Quantum Ferroelectrics
We discuss the possibility of weak first order transition in the domain of pressure induced phase transitions in a quantum ferroelectric as a consequence of order parameter fluctuations. We start with a semi-microscopic Hamiltonian, where polarization fluctuations are controlled by hydrostatic pressure via strain coupling, which above certain strength of coupling constant, kills second order tr...
