Figure 2: Properties of the a-CFTBO thin films.
From: A room-temperature magnetic semiconductor from a ferromagnetic metallic glass
(a) The optical transmission spectra of the a-CFTBO and the MG thin films at the same thickness of 25 nm. Left inset shows the Tauc plot derived from the transmission spectrum of the a-CFTBO thin film. Right inset shows its room-temperature photoluminescence (PL) spectrum. (b) The normalized resistivity ρ/ρ0 as a function of temperature (ρ0 is the room temperature resistivity). Inset is the plot of ln(ρ/ρ0) versus 1/T1/2 based on the experimental data. (c) Magnetic field dependence of the magnetization (M–H curves) measured at different temperatures. (d) Temperature dependence of the magnetization measured under an in-plane magnetic field of 100 Oe.
