a Experimental and projected dependence of the elastic (Young’s) modulus on the magnetic field for MREs with different levels of anisotropy. Point A marks peak experimental performance shown in Fig. 4. b Percentage normalized change in the starting γS and ending γE bandgap frequencies for experimentally obtained (solid black), superior (dashed red), and inferior (dashed blue) anisotropy levels at a constant magnetic field of 1600 Oe. c Percentage normalized change in the starting γS and ending γE bandgap frequencies corresponding to an increase in magnetic field beyond experimental limits, at the same anisotropy level of the MRE material.
