Feuerbacher et al, Mater. Res. Lett. 3, 1-6 (2015)]. The alloy obtains a hexagonal, single phase crystal structure. As the mutual mixing enthalpies of the elements are zero, the Ho-Dy-Y-Gd-Tb HEA may be considered as a prototype of an ideal HEA.</span></p><p style="color: #000000; font-family: 'times new roman', 'new york', times, serif; font-size: 12pt; margin: 15px; text-align: justify;" data-mce-style="color: #000000; font-family: 'times new roman', 'new york', times, serif; font-size: 12pt; margin: 15px; text-align: justify;"><span style="font-family: arial, helvetica, sans-serif;" data-mce-style="font-family: arial, helvetica, sans-serif;">We have studied magnetic properties, temperature dependent specific heat and electrical resistivity, and magnetoresistivity of the Ho–Dy–Y–Gd–Tb HEA and three additional members of the rare earth based HAEs: Ho-Tb-Dy-Gd-Lu, Ho-Tb-Dy-Er-Tm, and Ce-Gd-Tb-Dy-Ho.</span></p><p style="color: #000000; font-family: 'times new roman', 'new york', times, serif; font-size: 12pt; margin: 15px; text-align: justify;" data-mce-style="color: #000000; font-family: 'times new roman', 'new york', times, serif; font-size: 12pt; margin: 15px; text-align: justify;"><span style="font-family: arial, helvetica, sans-serif;" data-mce-style="font-family: arial, helvetica, sans-serif;">A typical magnetic phase diagram constructed from experimentally determined physical properties will be presented.
