Query: Anomalous itinerant magnetism in single crystal Sr4Ru3O10: A
  thermodynamic and transport investigation   A thermodynamic and transport study of Sr4Ru3O10 as a function of temperature
and magnetic field is presented. The central results include a growing specific
heat C with increasing field B, a magnetic contribution to C/T at low
temperatures proportional to -log(T), an abrupt jump and a peak in C/T at 2.90
T and 7 T for B||ab-plane and B||c-axis, respectively, and corresponding
changes in the low T power laws of the resistivity. The novelty of this work
lies in the fact that this system is strongly anisotropic displaying
spontaneous ferromagnetism along the c-axis and an intralayer metamagnetic
transition with a possibility of a nearby quantum critical point. The exotic
behavior reflects new physics that is yet to be understood.
