Abstract: The invention relates to high entropy alloy of rare earth elements (RE-HEAs) including at least four and up to twelve elements selected form rare earth elements R1,R2,R3,R4,R5,R6,R7,R8,R9,R10,R11,R12, which rare earth elements R1 to R12 each represents one of elements 57 to 60, 62 to 70, 39 and 40 of the periodic system and to high entropy alloy of transition elements (TM-HEAs) including at least 3 and up to 12 elements selected from transitional elements TM1,TM2,TM3,TM4,TM5,TM6,TM7,TM8,TM9,TM10,TM11,TM12, which transitional elements TM1 to TM12 each represent at least one of elements 21 to 30, 41 to 48 and 72 to 79 of the periodic system. Such RE-HEAs and/or TM-HEAs can be used as building blocks in magnetic high entropy composite alloys, e.g. of the type (RE-HEAs)x(TM-HEAs)yTz, for the manufacture of magnetic devices and permanent magnets.
