# Technical Document Extraction ## Image Description The image contains two primary components: 1. **Heatmaps (a, b)** showing energy loss distribution as a function of temperature and magnetic field 2. **Line graphs (c, d, e, f)** displaying temperature-dependent measurements of FWHM and peak height --- ## Heatmap Analysis (a, b) ### Axis Labels - **X-axis**: Temperature (K) [0-300 K] - **Y-axis**: Energy loss (eV) [1.4-2.4 eV] - **Color Scale**: Intensity (arbitrary units) [0.00-0.30] ### Key Features - Vertical dashed line at **Tc** (critical temperature) - Magnetic field values: - (a) H = -0.39 r.l.u. - (b) H = 0 r.l.u. - Energy regions labeled: - B1 (1.4-1.6 eV) - B2 (1.6-1.8 eV) - B3 (1.8-2.2 eV) - D1 (1.8-2.0 eV) - D2 (2.0-2.2 eV) ### Spatial Grounding - **Tc line**: ~200 K (vertical dashed line) - **B1 region**: Bottom of heatmap (1.4-1.6 eV) - **B3 region**: Top of heatmap (1.8-2.2 eV) - **D1/D2 regions**: Middle energy range (1.8-2.2 eV) --- ## Line Graph Analysis (c, d, e, f) ### Legend (Right Side) | Color | Label | Marker | |--------|-------|--------| | Orange | D1 | Circle | | Green | D2 | Square | | Blue | B1 | Triangle | | Red | B2 | Diamond | | Purple | B3 | Star | ### Graph (c): FWHM vs Temperature - **X-axis**: Temperature (K) [0-300] - **Y-axis**: FWHM (meV) [0-300] - **Trends**: - B3 (red): Sharp upward trend (200→300 K) - B2 (blue): Moderate increase (150→250 meV) - D1 (orange): Flat (~10 meV) - D2 (green): Slight increase (5→15 meV) ### Graph (d): FWHM vs Temperature (H=0) - Similar trends to (c) but with reduced magnitudes - B3: 100→200 meV - B2: 80→180 meV - D1: 5→10 meV - D2: 3→8 meV ### Graph (e): Peak Height vs Temperature - **Y-axis**: Peak height (arb. units) [0-0.3] - **Trends**: - B3 (purple): Decreasing (0.25→0.15) - B2 (red): Stable (0.15) - D1 (orange): Flat (0.05) - D2 (green): Decreasing (0.2→0.1) ### Graph (f): Peak Height vs Temperature (H=0) - Similar decreasing trends but with lower values - B3: 0.25→0.12 - B2: 0.15→0.08 - D1: 0.05→0.03 - D2: 0.2→0.1 --- ## Critical Observations 1. **Tc Correlation**: All graphs show significant changes at Tc (~200 K) 2. **Magnetic Field Effect**: - H = -0.39 r.l.u. shows stronger intensity variations - H = 0 r.l.u. exhibits more uniform distributions 3. **Peak Height Behavior**: - B3 consistently shows highest peak heights - D1 maintains lowest peak heights across all conditions --- ## Data Table Reconstruction | Region | H = -0.39 r.l.u. | H = 0 r.l.u. | |--------|------------------|--------------| | B1 | 0.12 arb.u. | 0.08 arb.u. | | B2 | 0.25 arb.u. | 0.20 arb.u. | | B3 | 0.30 arb.u. | 0.25 arb.u. | | D1 | 0.05 arb.u. | 0.04 arb.u. | | D2 | 0.15 arb.u. | 0.12 arb.u. | --- ## Language Note All text appears in English.
