lithium niobate / Data / curie-temperature

Curie temperature

Spread

T_C °C; one row per variant and wavelength

Each mark is one record; bars are stated ranges, whiskers stated uncertainties. Filled marks: P, P-comp, P-db; hollow: S, V, C, P(abs). Hover a mark for its source. Each row has its own axis; no mean or fit is drawn.
