CrFeCoNiCu is an fcc alloy that was found to be paramagnetic. But upon adding titanium, it forms a complex microstructure consisting of fcc solid solution, amorphous regions and nanoparticles of Laves phase, resulting in superparamagnetic behavior. High magnetic coercivity has been measured in a FeMnNiCoBi alloy. There are several magnetic high-entropy alloys which exhibit promising soft magnetic behavior with strong mechanical properties. Superconductivity was observed in TiZrNbHfTa alloys, with transition temperatures between 5.0 and 7.3 K.
