      abstract     = {AC susceptibility and neutron scattering measurements are
                      used to study the magnetic field-temperature magnetic phase
                      diagram of a Tb single crystal under uniaxial tension along
                      its hexagonal c axis. An external magnetic field is applied
                      in the basal plane. We focus on the region in the phase
                      diagram that corresponds to the helical antiferromagnetic
                      phase and find that this region collapses when the uniaxial
                      tension is increased beyond a critical value as low as 600
                      bar. There are strong reasons to associate this collapse
                      with an underlying Lifshitz transition in the Fermi surface
                      of Tb's valence electrons. We use a finite-temperature ab
                      initio theory to analyze our measurements, obtaining a
                      pressure-temperature magnetic phase diagram in very good
                      agreement with experiment. Our calculations indicate that
                      short- and long-range magnetic order has a crucial effect on
                      the Fermi surface nesting and consequent magnetism of Tb.},
