abstract = {Exploring the relations between coexisting, cooperative, or
competing types of ordering is a key to identify and harness
the mechanisms governing the mutual interactions between
them and to utilize their combined properties. We have
experimentally explored the response of the charge density
wave (CDW) to various antiferromagnetic, metamagnetic, and
field-aligned ferromagnetic states that constitute the
magnetic phase diagram of TmNiC$_2$. The high-resolution
x-ray diffraction experiment employing synchrotron radiation
at low temperature and high magnetic field allowed one to
follow the superstructure satellite reflections, being a
sensitive probe of CDW. This investigation not only reveals
direct evidence that the charge density wave avoids even a
partial suppression in the antiferromagnetic ground state,
but also proves that this state coexists, without any
visible signatures of weakening, in the entire dome of the
magnetically ordered phases, including the field-aligned
ferromagnetic state. The calculations of the electronic and
phonon structures support the experiment, revealing that the
dominant contribution to the CDW transition stems from
momentum-dependent electron-phonon coupling. We conclude
that this mechanism prevents the CDW from vanishing,
although the nesting conditions within the magnetically
ordered phases deteriorate.},
