Nonanalytic behavior of two-dimensional itinerant ferromagnets
journal contribution
posted on 2013-07-15, 10:46 authored by Dmitry V. Efremov, Joseph BetourasJoseph Betouras, Andrey ChubukovWe consider an ordered ferromagnet in the vicinity of a T=0 transition into a paramagnet. We
show that the free energy and the transverse and longitudinal static susceptibilities contain nonanalyticities
which destroy a continuous second-order transition. Depending on the parameters, the
transition either becomes first-order, or occurs via an intermediate spiral phase.
