      abstract     = {We present a study of the magnetic phase diagram and the
                      magnetoresistance of a Gd–Tb–Dy–Ho–Lu "ideal"
                      hexagonal high-entropy alloy (HEA), composed of the elements
                      from the heavy half of the rare earth series only. The phase
                      diagram contains an antiferromagnetic (AFM) state, a
                      field-induced ferromagnetic (FM) state above the AFM-to-FM
                      spin-flop transition and a low-temperature spin-glass state.
                      The complex phase diagram is a result of competition between
                      the periodic potential arising from the electronic band
                      structure that favors periodic magnetic ordering, the
                      substitutional-disorder-induced random local potential that
                      favors spin-glass-type spin freezing in random directions,
                      the Zeeman interaction with the external magnetic field that
                      favors spin alignment along the field direction and the
                      thermal agitation that opposes any spin ordering. The
                      magnetoresistance reflects complexity of the phase diagram.
                      Its temperature dependence can be explained by a continuous
                      weakening and final disappearance of the periodic potential
                      upon cooling that leads to the destruction of long-range
                      ordered periodic magnetic structures. The magnetoresistance
                      is large only at temperatures, where the AFM and
                      field-induced FM structures are present and exhibits a
                      maximum at the critical field of the AFM-to-FM transition.
                      Within the AFM phase, the magnetoresistance is positive with
                      a quadratic field dependence, whereas it is negative with a
                      logarithmic-like field dependence within the field-induced
                      FM phase. At lower temperatures, the long-range periodic
                      spin order "melts" and the magnetoresistance diminishes
                      until it totally vanishes within the low-temperature spin
                      glass phase. The magnetoresistance is asymmetric with
                      respect to the field sweep direction, reflecting
                      nonergodicity and frustration of the spin system.},
