Query: Phase diagram of CeSb$_2$ from magnetostriction and magnetization
  measurements: Evidence for ferrimagnetic and antiferromagnetic states   Cerium diantimonide (CeSb$_2$) is one of a family of rare earth based
magnetic materials that exhibit metamagnetism, enabling control of the magnetic
ground state through an applied magnetic field. At low temperatures, CeSb$_2$
hosts a rich phase diagram with multiple magnetically ordered phases for many
of which the order parameter is only poorly understood. In this paper, we
report a study of its metamagnetic properties by Scanning Tunneling Microscopy
(STM) and magnetization measurements. We use STM measurements to characterize
the sample magnetostriction with sub-picometer resolution from magnetic field
and temperature sweeps. This allows us to directly assess the bulk phase
diagram as a function of field and temperature and relate spectroscopic
features from tunneling spectroscopy to bulk phases. Our magnetostriction and
magnetisation measurements indicate that the low temperature ground state at
zero field is ferrimagnetic. Quasiparticle interference mapping shows evidence
for a reconstruction of the electronic structure close to the Fermi energy upon
entering the magnetically ordered phase.
