From: Reversible tuning of magnetocaloric Ni-Mn-Ga-Co films on ferroelectric PMN-PT substrates
Dependence of the magnetisation within the martensitic and mixed state on the electric field E applied to the PMN-PT substrate. (a) M(E) on heating (300 K) and cooling branch (280 K) in the martensitic phase. The magnetisation is not changed reversibly. (b) M(E) in the phase transition region on the cooling (320 K) and heating (345 K) branch. After an initial change of the magnetisation during the first cycle, the electric field change has almost no influence on the magnetisation anymore. All measurements were performed at μ0 H = 0.1 T.
