The temperature dependency of the viscoelastic properties of magnetorheological elastomers (MREs) operating in the shear mode was experimentally investigated under broad ranges of strain amplitude, excitation frequency, and applied magnetic field. Experiments were performed with isotropic MRE samples with ##IMG## [http://ej.iop.org/images/0964-1726/29/11/115001/smsabb359ieqn1.gif] {${\rm{25\% }}$} volume fraction of carbonyl iron particles dispersed in the silicone rubber matrix under controlled temperature, ranging from ##IMG## [http://ej.iop.org/images/0964-1726/29/11/115001/smsabb359ieqn2.gif] {$ - 10{\rm{ }}^\circ {\rm{ C}}$} to ##IMG## [http://ej.iop.org/images/0964-1726/29/11/115001/smsabb359ieqn3.gif] {$50{\text{}}^\circ {\text{C}}$} together with different levels of magnetic field density ( ##IMG## [http://ej.iop.org/images/0964-1726/29/11/115001/smsabb359ieqn4.gif] {$0$} to ##IMG##
