Abstract
To date, the only direct method to assess the strong magnetic fields of High-Mass X-ray Binaries
containing accreting neutron stars is the observation and analysis of electron cyclotron resonance
features (short: "cyclotron lines" or CRSFs) in their high-energy X-ray spectra. We dicuss how the
upcoming era of new observatories and instrumentation like IXO will change our "magnetic" view
of those objects. The science case for IXO in this respect does not focus on the measurement of the
cyclotron lines themselves (which are typically at 10–100 keV) but on obtaining new constraints
on the accreting sources’ geometries and physical parameters as key ingredients to disentangle
their influences and understand the overall timing and spectral properties of neutron star highmass X-ray binaries.
