摘要: Abstract A magnetoactive elastomer (MAE) consisting of single-domain La0.6Ag0.2Mn1.2O3 nanoparticles with a Curie temperature close to room (TC = 308 K) in silicone matrix has been prepared and comprehensively studied. It found that MAE particles are magnetized superparamagnetically low coercivity below 10 Oe at above. The influence magnetic anisotropy on the appearance torque is justified. coupling between magnetization magnetoelasticity also established. mechanisms magnetoelasticity, including effect rearrangement compression by particles, have revealed. magnetoelastic properties critical features near TC. disappear T > TC restored T
