Fig. 1: Positioning of our study in terms of responsivity with respect to the frequency map, and mechanism of the spin bolometer.
From: Uncooled sub-GHz spin bolometer driven by auto-oscillation
a Responsivities of rectification devices vs frequency. Blue and orange rectangular regions refer to bolometers and magnetic tunnel junctions (MTJs), respectively. Red point represents our result. b, c Schematic of spin bolometer (b) without and (c) with applied microwaves. Red and black arrows represent the magnetizations of the ferromagnetic free and pinned layers, respectively.
