Query: Temperature dependent bilayer ferromagnetism in Sr3Ru2O7   The Ruthenium based perovskites exhibit a wide variety of interesting
collective phenomena related to magnetism originating from the Ru 4d electrons.
Much remains unknown concerning the nature of magnetic fluctuations and
excitations in these systems. We present results of detailed inelastic neutron
scattering measurements of Sr3Ru2O7 as a function of temperature, probing the
ferromagnetic fluctuations of the bilayer structure. A magnetic response is
clearly visible for a range of temperatures, T = 3.8 K up to T = 100 K, and for
energy transfers between 2 and 14 meV. These measurements indicate that the
ferromagnetic fluctuations manifest in the bilayer structure factor persist to
surprisingly large temperatures. This behavior may be related to the proximity
of the system in zero magnetic field to the metamagnetic/ferromagnetic
transition.
