Multiferroic polymer composite based on Heusler-type magnetic microwires with combined magnetocaloric and magnetoelectric effects
Source abstract
Abstract
Abstract We have studied the magnetocaloric and magnetoelectric properties of a new type of the magnetoelectric composite that consisted of Heusler-type magnetic microwires embedded in a polyvinylidene fluoride piezoelectric polymer matrix fabricated using a modified solvent casting technique. The maximum of the adiabatic temperature change ΔT of ~ 0.04 K was observed around 276 K with narrow hysteresis accompanied with a maximum of magnetoelectric effect. Observed temperature dependences of the magnetocaloric and magnetoelectric effects can be associated with magnetic (paramagnetic-ferromagnetic) phase transition. The measurements of the magnetocaloric effect in modes with different frequencies (0.5–20 Hz) of the modulated magnetic field exhibit a reduction of ΔT about 38%.
